摘要
简单介绍了MC-CDMA系统,重点讨论了两种同步方案,即基于循环前缀、基于导频的同步方案。针对在有干扰存在的信道,分析这两种方案实现定时同步的可靠性。通过仿真,得出结论:基于导频的同步方案在噪声信道中能够准确实现定时同步,并且在有衰落存在的条件下,也能很好的实现定时同步。
In this paper MC-CDMA system is briefly introduced and two synchronization algorithms based on pilot and cycle prefix are discussed in detail. Simulation result shows that the algorithm based on pilot is better than the one based on cycle prefix, especially in the fading channel.
