OFDM 系统采样时钟同步算法
Sampling clock synchronization algorithm for OFDM system
摘要
Abstract
The paper presents a high precision and simple sampling clock synchronization algorithm with little overhead for OFDM system. The algorithm based on fine frequency estimation method estimates the sampling clock frequency spectrum bias, and then the improved Farrow filter converts the signal sampling rate to correct the deviation of the sampling clock frequency, and correct deflection of the phase due to the residual sampling clock skew using phase compensation. The simulation and analy⁃sis results show that the proposed algorithm can completely overcome the impact of the sampling clock frequency deviation on OFDM system and achieve high⁃precicion sampling clock synchronization.关键词
