本文提出当信道增益为时变函数时，利用自适应控制器来补偿信道增益的变化，以便在接收端能准确地恢复出信息信号。
In order to recover the message carrying signal at the receiving end, we use adaptive controller to compensate the variation of channel gain when the channel is time-varying.
该方法应用改进冗余位结构，通过在其子dac输出端引入伪随机信号测量级间增益，并利用此估计值在后台进行增益误差补偿。
Using a reformative redundant stage, gain errors are measured by PR (pseudo-random) signal being injected at sub-DAC output and compensated in background according to the estimated value.
