商分编码QAM由于无需信道估计和均衡，因此降低了在瑞利衰落信道解调的复杂性。
Due to no channel estimation required for Rayleigh fading channel, quotient coded QAM has lower receiver complexity.
对于传统的OFDM系统来说，如果循环前缀的长度大于信道的时延扩散值，则可以通过简单的频域均衡来解调OF DM信号。
If the length of its cyclic prefix is larger than the delay spread of transmission channel, we can get a simple frequency equalizer to demodulate OFDM signal.
