摘要
介绍了采用已知序列UW(uniqueword)帧格式的单载波频域均衡(singlecarriersystemwithfrequencydomainequalization,SC_FDE)系统,研究分析了其同步问题,给出了频率同步和定时同步算法,并对接受星座图和系统的误码性能进行了仿真.结果表明,该算法较好地解决了SCFDE系统的同步问题.
The single carrier system with frequency domain equalization（SC-FDE） using a known sequence（ unique word, UW） is introduced. The effeet of frequency and timing offset are analyzed and a method of frequency and timing synchronization is proposed. The received constellation and the BER of the system are simulated. Results show that the method can solve the synchronization question in the SC-FDE system.
