With knowing the information of source signals and transmission channel, we can carry on processing to the signals, filter out interfering signals and get useful signals.

在知道源信号信息和传输信道的情况下，我们可以对信号进行处理，滤除干扰信号，得到有用信号。

However, for such high-speed data transmissions, the channel is severely frequency-selective due to the presence of many interfering paths with different time delays.

但是，对于这样高速率的传输，信道会由于具有不同延迟时间的多条干扰路径的存在而呈现出严重的频率选择性。
