介绍OFDM与基于块传输单载波通信系统的技术对比,以及单载波系统的关键技术频域均衡的两种算法。由于单载波系统传输时加入了UW（Unique Word）符号,使其在接收端的频域均衡技术大大简化。它与多载波OFDM通信系统相比较有相似的抗干扰性能和较小的峰均比特性,是对未来通信系统多载波传输的一个有利补充。

This paper mainly introduces the comparison of the capability of Orthogonal Frequency Division Multiplexing（OFDM） and signal carrier system based on block transmission,as well as another two key technologies about frequency domain equalization（FDE）.Due to the use of the Unique Word（UW） in signal carrier transmission system,here the FDE technology at receiver is to certain extent simplified.Although the signal carrier system has similar ability of resistance to interference compared to OFDM,the much lower PAPR makes signal carrier system a good technology in the development of communication system.
