介绍了分组传输系统频域均衡器的结构和设计方法，并研究了其误码率（BER）性能。
In the paper, we introduce the structure of frequency -domain equalizer and its design. its BER performance are also studied.
本文设计的均衡器采用了时域和频域联合处理的自适应均衡技术，其中频域均衡作为DFE的前馈滤波部分，时域的反馈滤波的部分使用常规的横向滤波器。
The equalization in frequency domain is the feed-forward filtering of the DFE. And the traditional transversal filter is used in the feed-back filtering in time domain.
与时域均衡器的比较表明，频域均衡可较大地改善分组传输系统的均衡效果，缺点是接收端的计算量有所增加。
The simulation results show that the frequency-domain equalization approach can improve the BER performance great-ly than the time -domain equalization. The drawback of the…
