Research Initiation: Adaptive Coding on Nonstationary Channels with Feedback

针对带反馈的非平稳通信信道，提出了一种自适应差错控制算法。反馈信道允许将信道状态信息从接收器流动到发射器。发射机使用该信息根据信道噪声和衰减的变化来重新配置数据结构。在开发自适应算法时，需要考虑三个基本问题。首先，接收器如何从接收到的数据块中获得信道状态信息？其次，接收方如何使用反馈通道将该信息报告给发送方？最后，发送者对此信息作何反应？

This study is developing adaptive error control algorithms for nonstationary communication channels with feedback. The feedback channel allows for the flow of channel state information from the receiver to the transmitter. The transmitter uses this information to reconfigure data structures in accordance with variations in channel noise and attenuation. There are three basic questions that are being considered in the development of the adaptive algorithms. First, how can the receiver derive channel state information from received data blocks? secondly, how can the receiver use the feedback channel to report this information to the transmitter? Finally, how is the transmitter to react to this information?
