摘要

In order to improve the data processing speed of modem and realize high speed data transmission,this paper studies the parallel modulation and demodulation algorithm of Gbit level,mainly including parallel carrier recovery algorithm,parallel clock recovery algorithm and parallel channel estimation and equalization algorithm. The simulations are performed for system performance under AWGN channel using matlab software.The results show that the parallel modulation and demodulation algorithm can effectively improve data processing speed of system,and the system has a better error performance.%为了提高调制解调器数据处理速度，实现高速数据传输，针对 Gbit 级无线通信中并行调制解调算法展开研究，提出并行Gardner时钟恢复算法、并行载波恢复算法及并行信道估计与均衡算法，并利用matlab软件对 AWGN 信道下系统性能进行仿真验证。仿真结果表明，所提出的并行调制解调算法，可有效提高系统的数据处理速度，且系统具有较优的差错性能。
