Abstract

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.

一种用于OFDM的高效率均衡技术

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。
