摘要
提出一个基于循环前缀的OFDM系统符号同步算法的硬件实现方案,讨论了实现中要考虑的各种问题,同时对现有的算法进行简化及提出了优化同步性能的方法,并能用较简单的硬件结构来实现,同时给出相应的仿真结果与实现结构。
Symbol synchronization estimation is very important to OFDM systems. Redundant information contained within the cyclic prefix enables this estimation without additional pilots. A realization scheme for CP based symbol synchronization is proposed which could be implemented with lower hardware complexity. Analysis and simulation results were also provided.
