采用最小似然bit同步的QPSK系统的性能分析

Property Analysis of QPSK System Using the Minmum Likelihood Bit Synchronization

本文分析了简单的ＱＰＳＫ系统采用最小似然ｂｉｔ同步时，其定时误差对系统抗噪性能产生的影响并给出了系统定时误差的均方差与电路各参数间的关系。

In this paper, the performance of QPSK system using the Minimum Likelihood bit synchornization is analyzed. The timing-error of bit synchronization and the bit error rate of this system is also discussed.
