At the beginning of this thesis, we introduce the fundamental of the acoustics and the perceptual mechanism. next, different kinds of speech processing methods including time processing and time - frequency analysis are presented, such as short time average energy, short time cross zero analyses, short time autocorrelation function analyses and fft. at last, we focus on the sound separation, especially on single channel sound separation
在這篇文章開始的部分，我們介紹了聲學的基礎知識和人類聲音感知的機理;接下來，我們給出了在時域處理和頻域處理語音信號的一些經典的技術，比如短時平均能量分析、短時過零分析、短時自相關函數分析、快速傅立葉變換等;本文重點從理論和實驗上討論語音分離，特別是單聲道語音分離的演算法及其在分離音樂鼓點中應用。Based on the two ex isting underwater acoustic channel models ( the rice model and the rayleigh model ), we simulated the effects on the image signal underwater transmission with different ofdm parameters. by selecting appropriate ofdm parameters, we realize a simple offline communication system. besides, parts of programs based on ti tms320c62x are realized in this thesis
本研究先根據現有的兩類水聲通道模型（萊斯衰落模型和瑞利衰落模型） ，藉助于計算機模擬，詳細考察不同的ofdm參數對于圖像信號水聲傳輸的影響，然後根據模擬的結果，選擇適當的參數實現了一個簡單的脫機（ offline ）通信系統，最後在ti公司的tms320c62x上實現部分相應的通信模塊。
