constant parameter channel的意思|示意

The transmission of the earth wave is stable, hardly influenced by climate and its channel parameter does not change with time basically, it is Constant Parameter Channel.

地波传播受天气的影响较小，比较稳定，信道参数基本上不随时间的变化而变化，是恒参信道。

In the channel output, subspace decomposition is employed. If the signal subspace can be exclusively decided by the channel, the parameter of the channel can be estimated by a constant.

在信道输出端进行子空间分解，如果信号子空间是由信道唯一决定的，那么信道参数可被唯一估计为一个常数。
