Synchronization Algorithm for OFDM Frequency with Repeated Sequence and Cyclic Prefix(CP) 利用重复序列和循环前缀(CP)的OFDM频率同步算法
Although traditional algorithm which combines cyclic prefix ( CP ) with pilot carrier is very effective to frequency offset estimation, its computational complexity is high. 传统的基于导频和循环前缀(CP)的算法虽对频偏估计很有效,但计算复杂度较高。
