+LaTeX Template for Presentations
+================================
+
+This package serves as a template for presentations in the [Corporate Design of KIT](https://kit-cd.sts.kit.edu/praesentationen.php) (version from February 2025).
+
+It is modified from the template developed by the research group [DSiS](https://dsis.kastel.kit.edu) at the KIT Faculty of Computer Science and is based on [LaTeX Beamer](https://ctan.org/pkg/beamer).
+See https://sdq.kastel.kit.edu/wiki/Dokumentvorlagen
+
+Modified by: [Dr.-Ing. Hedongliang Liu]
+
+Compile the `introduction.tex` to see an example.
+
+# Usage
+
+## `Options` for the "CELbeamer" document class
+------------------------------------------
+The font size in the footer is set larger by default than in the PowerPoint template. This can be enforced to match the original specification using the `smallfoot` option.
+
+| Footer font size         | Option               |
+| ---------------------    | -------------------- |
+| slightly larger (12pt)   | `bigfoot` (default)  |
+| KIT specification (11pt) | `smallfoot`          |
+
+German and English are available as languages. The language selection automatically sets the appropriate formats (e.g., quotation marks, date).
+
+| Language  | Option          |
+| --------- | --------------- |
+| German    | `de`            |
+| English   | `en`  (default) |
+
+Slide titles are set in Helvetica. If you want Franklin Gothic for everything, you can define this.
+
+| Title font        | Option                |
+| ----------------- | --------------------- |
+| Franklin Gothic   | `franklin`            |
+| Helvetica         | `helvet`  (default)   |
+
+### Other options
+- The navigation bar in the footer can be enabled using the `navbaron` option.
+
+- With the `kitgrid` option, the grid of the slides can be displayed.
+
+- The `handout` option turns off the animations. Multiple slides for the same frame will be shown on one slide, or according to the commands in the animation instructions. 
+E.g., `\only<2|handout:0>{This is not shown in handout mode.}`, `\item<1-|handout:2>{This shows only on the second slide of the frame in the handout mode.}`
+
+- The `spaceforface` option leaves extra space on the right-hand-side of the frame to put presenter's video. The width of the space can be adjusted by changing the <width> in \setlength{\spaceforface}{<width>} in `CELbeamer.cls`.
+
+- The `overviewatsection` option displays the table of contents at each section. Only subsections of the current section is shown.
+
+- The `showsubsectionsatfirstoverview` option shows all the subsections at the first overview. This requires `overviewatsection` option.
+
+Example: `\documentclass[de, navbaron, kitgrid, handout, overviewatsection]{CELbeamer}`
+
+## Title Slide
+Setup: `\begin{frame}[title white vertical, picture=images/...., fundings=]`
+
+The image on the title slide can be set with the `picture=` option. For vertical layouts, the image fits the height; for horizontal layouts, it fits the width.
+
+Additionally, for horizontal layouts, you can choose the color of the KIT logo.
+
+| KIT logo color | Frame Option             |
+| -------------- | ------------------------ |
+| colored        | `kitlogo=rgb`            |
+| white          | `kitlogo=white`          |
+| black          | `kitlogo=black`          |
+
+Example: `\begin{frame}[title white horizontal, picture=images/palladio_bauplan, kitlogo=black]`
+
+## Special Slides
+### Table of content
+For tables of contents, you can specify the option `tableofcontents=<color>`, where `color` can be either `blue` or `green`. The table of contents will then be shown on a fully colored slide.
+
+### Image slides
+There are also special layouts for divider slides with large images. You can select them using frame options.
+
+| Vertical image share: | Frame Option                   |
+| --------------------- | ------------------------------ |
+| 33%                   | `picture 33 vertical`          |
+| 50%                   | `picture 50 vertical`          |
+| 66%                   | `picture 66 vertical`          |
+| arbitrary             | `picture vertical=<value in %>`|
+
+The image is set with the option `picture=<path>`, where `path` must be given relative to the main document.
+
+Logo and Name of Department/KIT Faculty/Institute
+-------------------------------------------------
+
+The logo at the bottom right of the title slide can be set with the following command:
+
+`\grouplogo{mylogo}` (without file extension)
+
+To use your own logo, place the file (e.g., `mylogo.pdf`) in the `logos/` directory and adjust the command. If no logo should be included, use `\grouplogo{}`.
+
+The group name can be set with the following command:
+
+`\groupname{Communication Engineering Lab}`
+
+The group name appears in the footer at the bottom right. Long names will be wrapped into two lines. If the group name is left empty (`\groupname{}`), the full width of the footer will be used for author names and title.
+
+The default width of the group name is 89 mm. It can be changed with
+
+`\groupnamewidth{120mm}`
+
+which also adjusts the width of the author and title text field accordingly. Line breaks are possible with `\\`. Instead of two-line footers, the `smallfoot` option may be preferable.

+\section{Other Tips}
+\subsection{Citations}
+\begin{frame}{Citations in Footnote using BibLaTeX}
+  Citations in beamer were often dealed bypasting the full text. \\
+  The biblatex package enables citing from your .bib file. \\
+  Here are several examples of usage:\\[-.5em]
+  \begin{itemize}
+	\item Cite full text in footnote \footfullcite{Rode23ECOC} by \texttt{$\backslash$footfullcite}.
+	\item If the mark is not wanted, combine \texttt{$\backslash$nomarkfootnote} and \texttt{$\backslash$fullcite}. \nomarkfootnote{\fullcite{Rode23JLT}}
+ 	\item Cite author and year in text \citeauthor{Rode23JLT}, \citeyear{Rode23JLT}.
+  	\item Cite title in text \citetitle{Karanov18JLT}.
+	\item Use \texttt{$\backslash$supercite} to cite the alphabetic bibkey \supercite{li2018achievable,Karanov18JLT}.
+\end{itemize}
+\textit{\footnotesize For more usage please refer to \href{http://tug.ctan.org/info/biblatex-cheatsheet/biblatex-cheatsheet.pdf}{\textcolor{kit-blue}{Biblatex Cheat Sheet}}.}
+%   \vspace{-1em}
+%   You can print all references that are cited at the end of presentation, as shown in the next slide.
+\end{frame}
+
+\begin{frame}{Cite in \emph{CEL} Style}
+% 	% Cite the reference in text by 
+	Cite the in text by \texttt{$\backslash$citereference\{\textcolor{kit-green}{<bibkey>}\}}. 
+E.g., 
+ 	\begin{itemize}
+ 		\item End-to-end learning applied to optimize multidimensional constellations for IM/DD links~\citereference{Karanov18JLT}
+ 		\item End-to-end learning of transceivers for the nonlinear Fourier transform~\citereference{gaiarin2020end}
+ 		\item Constellation optimization for the zero-dispersion channel~\citereference{li2018achievable}
+ 	\end{itemize}
+
+
+	Then add the references at the bottom of the page by \texttt{$\backslash$addreference\{<bibid>\}} for single reference, or \texttt{$\backslash$addreferences\{<bibid><bibid>...<bibid>$\backslash$stoppreferences\}} for multiple references.
+	\bigskip

+% % \textbf{\textcolor{kit-red}{Current bug:} If the last reference in \texttt{$\backslash$addreference} has two lines, the slide will be split into two, one only has the title and one only has the content.}
+% \end{frame}
+
+\subsection{Handout Mode}
+\begin{frame}{Handout Mode}
+	Handout mode is activated by the option \texttt{handout} in the document class.\\
+	A frame with multiple animated slides will be shown on one slide in the handout version.\\
+	One can still control the number of slides of one frame in the handout version, e.g.,
+	\begin{itemize}
+        \only<1|handout:0>{\item One: This will not be shown in the handout version.}
+        \only<2-|handout:1->{\item \textcolor{red}{One:} This is shown on the first slide of this frame in the handout version.}
+        \only<1|handout:0>{\item Two: This will not be shown in the handout version.}
+        \only<2-|handout:1->{\item \textcolor{blue}{Two:} This is also shown on the first slide in the handout version.}
+		\item<only@3|handout:2>{Three: This is shown on the second slide in the handout version.}
+		\item<only@4|handout:2>{Four: This is also shown on the second slide in the handout version.}
+    \end{itemize}
+\end{frame}
+
+\subsection{Macros}
+\begin{frame}{Predefined Macros}
+	\begin{itemize}
+		\item \schlagwort{Schlagwort} for highlighting keywords
+		\item An important thing \mind for pointing out important things
+		% \item \endofproof for a colored small box representing the end of a proof
+	\end{itemize}
+	Math macros
+	\begin{itemize}
+		\item \texttt{$\backslash$coloneq} $\coloneq$ for defining a new variable, e.g., $a \coloneq b + c$
+		\item \texttt{$\backslash$myspan$\{\cdot\}$} for span notation, e.g. $\myspan{\ba,\bb,\bc}$
+		\item \texttt{$\backslash$ceil$\{\cdot\}$} $\ceil{x}$ for ceiling function, e.g., $\ceil{3.14} = 4$
+		\item \texttt{$\backslash$floor$\{\cdot\}$} $\floor{x}$ for floor function, e.g., $\floor{3.14} = 3$
+		\item \texttt{$\backslash$dd} for differential operator, e.g., $\int f(x) \dd x$, $\frac{\dd f(x)}{\dd x}$
+		\item \texttt{$\backslash$real} $\real$ for real part, e.g., $\real(z)$
+		\item \texttt{$\backslash$imag} $\imag$ for imaginary part, e.g., $\imag(z)$ 
+	\end{itemize}
+\end{frame}
+
+\begin{frame}{Math Macros (Cont'd)}
+	\begin{itemize}
+		\item \texttt{$\backslash$sinc} $\sinc(x)$ for sinc function, e.g., $\sinc(x) = \frac{\sin(\pi x)}{\pi x}$
+		\item \texttt{$\backslash$rect} $\rect(x)$ for rectangular function, e.g., $\rect(x) = \begin{cases} 1 & |x| \leq \frac{1}{2} \\ 0 & \text{otherwise} \end{cases}$
