3. studying still image transmission systems without channel coding or with turbo codes over both awgn and rayleigh fading channels by matlab simulation. simulation results show that turbo codes not only advance the dependability of communication systems, but also reduce channel signal - to - noise ratio ( snr )
將turbo碼應用於靜止圖像傳輸系統，信源編碼採用矢量量化編碼，分別在awgn通道和rayleigh衰落通道下，對不採用通道編碼和採用turbo碼作為通道編碼的各種情況進行模擬。They still need to be studied. this thesis systematically studies the performances of turbo codes over both awgn channels and rayleigh fading channels, and discusses the applications of turbo codes in still image transmission systems. some significative conclusions are obtained
本文系統地研究了turbo碼在awgn通道和rayleigh衰落通道下的性能，並探討了turbo碼在靜止圖像傳輸系統中的應用，取得了一些有意義的成果。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。
