摘要

在正交频分复用(OFDM)系统中，如果其循环前缀的长度大于信道的延迟扩展，我们可以得到一个简单的频率均衡器来解调OFDM信号。但是，循环前缀的使用大大降低了传输效率。为此，提出了一种新的均衡结构，提高了OFDM系统的传输效率。

A high efficiency equalization used in OFDM

In OFDM (Orthogonal Frequency Division Multiplexing) system, if the length of its cyclic prefix is larger than the delay spread of channel, we can get a simple frequency equalizer to demodulate OFDM signal. However, the use of cyclic prefix degrades the efficiency of transmission greatly. So, we give a new equalizing structure, which improve the efficiency of transmission of OFDM system.
