  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。
  3. So it is necessary to add an equalizer to the physical receiver. it can enhance the adaptability of broadband digital transmission apparatus and effectively decrease the performance requirement of channel and receiver, accordingly can reduce cost

    因此，在實際的通信接收設備中加入均衡器是非常必要的，它可以提高寬帶數字傳輸設備的適應能力，有效降低通道、通道和接收設備的性能要求，節約成本。
  4. As one of the key techniques of new generation mobile communication systems and broadband wireless communications systems, " adaptive transmission " technique can exploit potential channel transmission ability sufficiently so that it enables the systems to reach the maximum transmission capacity and reliability by dynamically adjusting transmission parameters according to channel estimation and traffic qos requirement

    自適應傳輸技術是新一代移動通信和智能傳輸的核心技術之一。自適應調制是根據通道的實時狀態以及業務的不同特性動態調整傳輸參數，從而可以充分挖掘系統的傳輸潛力，提高頻譜利用率，以獲得最大的傳輸容量和最高的可靠性。
