CDMA系统频偏相偏补偿算法的改进与实现
Improvement and Implementation of Frequency and Phase Compensation Algorithm Based on CDMA System
摘要
Abstract
In view of the importance of frequency offset estimation in the downlink synchronization for CD-MA2000 system and the disadvantage of the time-frequency two-dimensional traditional joint estimation al-gorithm’s high computational complexity and insensitivity for the tracking frequency offset state,this paper proposes an algorithm of frequency offset correction based on pilot signal, which can achieve frequency off-set and phase offset compensation even for the maximum frequency offset. The experimental results show that the algorithm can realize frequency offset correction continuously and rapidly in CDMA2000 high-speed mobile environment.关键词
