摘要
鉴于信号载波频率偏差引起较大的误码等缺点,在Gardner改进算法(E-Gardner)的基础上提出了一种抗载波偏差的时钟误差检测算法(AC-Gardner),该算法解决了E-Gardner算法受载波频差和相差影响的问题。仿真结果表明,在Corazza信道环境下AC-Gardner算法能有效地消除载波偏差的影响,提高了整个系统的同步性能。
In view of disadvantage of the larger bit error rate caused by signals＇ carrier frequency deviation, this paper pro- poses a clock error detection algorithm of anti carrier deviation（AC-Gardner） based on the evolved Gardner algorithm（E-Gardner）, which solves the problem that E-Gardner algorithm is easily influenced by carrier frequency offset and phase offset. Simulation re- sults show that AC-Gardner algorithm can effectively eliminate the effect of carrier deviation, and improve the synchronization per- formance of the whole system under Corazza channel environment.
