摘要
在分析插值滤波器和均衡器的基础上,讨论了一种自适应插值的定时恢复算法,并进行了仿真。仿真结果表明,这一方法优于拉格朗日插值算法和LMS均衡算法。该算法在完成了对定时误差的插值运算的同时,也消除了衰落引起的码间干扰,性能良好。
A symbol timing recovery with adaptive interpolation based on interpolation filter and equalizer is discussed and its performance is investigated by simulation. The simulation results show that the algorithm is better than Lagrange interpolator and LMS equalize algorithm. It can achieve a better performance and mitigate both timing error and inter-symbol interference due to multipath fading.
