摘　　要：载波恢复与均衡是现代数字通信系统中接收机的两个重要组成部分,为了降低硬件的复杂性,往往将这两部分放在一起实行联合控制.分析了这种联合控制的优缺点,并针对其缺点提出了解决的方案.在Matlab6.0平台上的仿真结果表明,提出的方案有较好的效果.Carrier recovery and equalizing are two important parts of the receivers in modern digital communication systems. In order to reduce the complexity, these two parts are put together to control jointly. The advantage and disadvantage of the joint control were analyzed, and a scheme was proposed to overcome the straw back. Furthermore the proposed scheme was evaluated by simulation on Matlab 6.0. The simulation results showed that the proposed scheme works effectively.
