摘要

针对 5G 通信无线多媒体传输时域同步—正交频分复用（TDS-OFDM）系统中的符号定时恢复处理慢、性能距离理论界较大等问题，提出了一种并行MAP定时恢复算法。它通过拉格朗日插值，能较好地提取最佳采样点幅度与极性变化信息，检测定时误差。而且该算法采用了高效并行的最大后验概率（MAP）准则，高速完成定时误差估计。仿真表明，与现有MM算法、Gardner算法等相比，该算法估计精度较高，结果逼近MAP定时恢复算法，差距约2 dB。

Abstract

According to the problems of the existing timing recovery algorithm with the time-domain orthogonal frequency division multiplexing (TDS-OFDM) modulation in the wireless multimedia transmissions of 5G communications

such as slow processing speed and big theoretical distance

a parallel MAP timing recovery algorithm was proposed.Specifically

the Lagrangian interpolation was used and the amplitude and polarity change of the optimal sampling points were extracted to detect the timing error efficiently.Meanwhile

with the parallel maximum a posteriori (MAP) criterion

the timing error estimate was obtained at high speed.The simulation results show that the accuracy of the proposed algorithm is improved

when comparing with the existing MM algorithm

Gardner algorithm and others.The estimation result is very close to the MAP timing recovery algorithm

the difference is about 2 dB.
