一种基于最小均方误差原理的位同步捕捉算法

摘要

提出一种数字通信系统中基于最小均方误差原理的位同步捕捉算法,对算法的提出、原理以及性能进行了理论分析,同时在加性高斯白噪声信道下进行了大量的计算机仿真,给出了在某无线通信系统中的应用结果.此算法通用性强,实现位同步捕捉速度快,易于高速单片机及DSP实现,具有良好的抗噪性能.%This paper presents a new capture algorithm of bit synchronisation based on MMSE theory in digital communication system, the theory analyses on algorithm presence, principles and performances are given, meanwhile, quite a few computer simulation are done at the channel with additive white Gaussian noise ( AWGN ), and the application result in certain wireless communication system is provided as well. This algorithm has advantages of universal property, quicker synchronisation capturing speed and better noise robust, and is also easy to be implemented with high speed MCU and DSP.
