摘要 在对OFDM系统中由于多径时延效应带来的ISI和ICI分析的基础上,介绍了循环前缀的基本原理,提出了利用循环前缀实现消除OFDM系统中存在的ISI和ICI的符号定界同步算法;分析了算法的实现过程和相关理论,得出了算法的近似表达式和性能模拟结果。 Based on the analysis of ISI and ICI caused by multipath delay effect in OFDM system,the radical principle of cyclic prefix is introduced and the symbol demarcation synchronous algorithm is proposed to eliminate ISI and ICI occur- ring in OFDM system using cyclic prefix.Realization process about demarcation synchronous algorithm and correlative theory are analysed and the approximate expression is educed.The simulation result of performance is given in the end.
