OFDM系统通过在时域符号前插入大于信道冲击响应长度的循环前缀（CP）可以避免符号间干扰(ISI)和载波间干扰(ICI)。但是，过长CP会使得数据传输效率降低。可以采用最小均方误差（MMSE）信道缩短均衡技术来压缩信道冲击响应长度。-OFDM systems avoid inter-symbol interference (ISI) and inter-carrier interference (ICI) by inserting a cyclic prefix (CP) larger than the channel impulse response length before the time-domain symbol. However, long CP will reduce the efficiency of data transmission. A minimum mean square error (MMSE) channel shortening equalization technique may be employed to compress the channel impulse response length.
