  1. Delivering quality video over wireless channels in real time is a challenging task. this isprimarily because of the throughput of a wireless channel may be reduced due to multipath fading, cochannel interference, and noise disturbance. therefore, there is a critical need forrobust transmission of video over wireless channels. recently, the emergence of mimo - ofdm has stimulated great interest in real time video communication, because this system can offer broadband for the multimedia data transmission over wireless channels

    因為傳統的視頻壓縮技術是針對單天線系統，只產生單一的比特流，這與多天線系統不相適應，為此，需要將視頻信號分解成相應的多個碼流。本文探討一種將能視頻信號分解成多個碼流的多描述編碼方法，以適應多天線系統的傳輸。
  2. Data transmission in mobile channel with high speed and reliability is required in future mobile communication system. the 4th mobile communication system is expected to provide high - quality broadband services using the minimum possible resources ( power, bandwidth, complexity ). toward this end, an appropriate transmission technique that matches the mobile channel characteristics is required

    在移動通道環境中可靠、高速的傳輸數據是移動通信技術發展的目標和要求，並且第四代移動通信系統要求能夠以最低的代價（帶寬、功率、復雜性）來為各種用戶提供高質量的寬帶業務，這就需要有適于移動通道的傳輸技術來支持。
