分组传输系统的频域均衡
Frequency-Domain Equalization for Block Transmission Systems
【摘要】 通常分组传输系统都采用时域均衡,介绍一种分组传输系统的频域均衡方法。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。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。
【Abstract】 In block transmission systems,the c hannel is usually equalized in time -domain.This paper presents a frequency -domain e qualization approach for the system s.In the paper,we introduce the structure of frequency -domain equalizer and its design.its BER perform ance are also studied.The simula-tion results show that the frequency-domain equalization approach can i mprove the BER performance great-ly than the time -domain equalizatio n.The drawback of the frequency -dom ain equalization approach is that it increases the calculations a t the receiver in somewhat.
