2. 操作環境 LaTeX (F10) save (F2) PS2PDF (Alt+F11) dvi2ps (F11) 檔案標籤

3. 常用快速鍵 • 存檔 (F2) • 尋找 (F5) • 取代 (F6) • 復原 (Ctrl+z) • 剪下(Ctrl+x)、複製 (Ctrl+c)、貼上(Ctrl+v) • 編輯LaTeX的順序： • F10 → F10 →F11→ alt+F11

4. 英文輸入原則 • 空一行即開始新的一段 • 輸入一個空白跟多個連續的空白，編輯後都只會有一個空白 • 要輸入多個空白用~ • 新的一段開始會自動保留與前段間距，如不保留在前一段的最末處加\par • 新的一段開始會自動內縮，如不內縮在前頭加上\noindent • 粗體 \textbf{粗體}斜體\textit{斜體} 正體 \txtrm{正體}

5. 文稿結構 \documentclass[12pt,a4paper]{article} \begin{document} \newpage \setcounter{page}{1} \pagenumbering{roman} \tableofcontents \newpage \listoffigures \newpage \listoftables \fontsize{12}{24pt}\selectfont \newpage \setcounter{page}{1} \pagenumbering{arabic} \section{Introduction} \section{System Model} \subsection{OFDM systems} \subsubsection{Transmitter} \end{document}

6. 常用指令 • 開始新的一頁 \newpage • 本頁不顯示頁碼 \thispagestyle{empty} • 設定頁碼計數器值 \setcounter{page}{1} • 設定字體大小與行高 \fontsize{12}{24pt}\selectfont

7. 方程式 • 文章中要輸入方程式或變數用寫在 $$裡面 • vector $\mathbf{g}$→ vector g • $X_k[n]$ → Xk[n] • $X^{2m}$ → X2m • 輸入單行方程式與文字一起排版 \begin{equation} X=Y+Z \end{equation}

8. 方程式 • \usepackage{amsmath} • 輸入多行方程式與文字一起排版 \begin{align} X&=Y+Z,\\ a&=b+c. \end{align} • 不給編號 \notag • 自訂編號 \tag{5}

9. 方程式 • \usepackage{array} • 矩陣 \left[\begin{array}{cc} 1 & 2 \\ 3 & 4 \end{array}\right] • x[n]=\left\{\begin{array}{cc} \frac{1}{2}, & n=0\\0,&\textrm{otherwise}\end{array}\right.

10. 圖片 \begin{figure}[t] \centering \includegraphics[width = 6.5in]{OFDM_PAPR_JNL_fig02.eps} \caption{Architecture of Proposed Scheme III.}\label{PS_III} \end{figure}

11. 圖片 • 在LaTeX中，圖片要使用eps檔 • 如何獲得eps檔： • MATLAB：直接save as，檔案類型選eps • VISIO： • 先到頁面設定→紙張大小→選大小符合繪圖內容 • 另存新檔為PDF檔，再使用Acrobat Professional另存eps檔。
