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.
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。
The experiment shows that the bandwidth of the time delay as a function of the modulation frequency changes in the absorption and gain regimes due to the carrier-lifetime variation.
实验结果表明，由于载体寿命的变化，在吸收和增益区域，带宽的时滞随着调制频率的变化而变化。
