Because the outgoingsignal is known, it is as easy to process as spread-spectrum signals.
正因为输出信号是已知的,所以它能更轻松地处理这样多频率的信号。

But because the outgoingsignal is not known it takes more processing to match it to the return.
不过,由于输出信号不规则,它必须进行更多的的数据处理以匹配返回信号。

The traditional way around the problem is to have radios communicating on the same frequency take turns transmitting so the outgoingsignal doesn't interfere with the incoming.
