Description: 为了减少无线信道中存在的多径和频偏对中国移动多媒体广播(CMMB)系统传输信号同步的影响，本文结合CMMB标准协议规定的具体帧结构，分析了符号同步对系统的影响，讨论了传统最大似然(ML)算法的优缺点，并基于文献中的无数据辅助算法，提出了一种适合该系统并且复杂度较低的粗符号定时同步算法。仿真结果表明，在AWGN及多径信道环境下，新算法可以有效克服传统算法相关峰不明显的缺陷，其估计性能更好-In order to reduce the influence for synchronization of signals in CMMB (China Mobile Multimedia Broadcasting) system, which caused by multi-path and frequency offset in wireless channel. This paper combined the specific frame structure of CMMB standard protocol, analyzed the impact of symbol synchronization, discussed advantages and disadvantages of the traditional ML (Maximum Likelihood) algorithm, and based on the non-data auxiliary algorithm in literature, proposed a coarse symbol timing synchronization algorithm, it is suitable for the system and its complexity is very low. Simulation results show that the new algorithmof signals in CMMB Platform: |
