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?

本研究开发自适应误差控制算法 用于具有反馈的非平稳通信信道。 的 反馈信道允许信道状态信息的流动 从接收器到发送器。 发射机用这个 信息，以根据 信道噪声和衰减的变化。 有三个基本问题正在考虑中， 自适应算法的发展。 第一，如何能 接收机从接收数据中导出信道状态信息 街区？ 第二，接收方如何使用反馈信道 向发射机报告这个信息 最后， 发送器对这个信息做出反应？
