摘要
文中描述了基带均衡通信系统的信号模型,研究了基于此模型的三个典型的Bussgang均衡器:恒模算法(CMA),Sato和直接判决(DD)均衡器。给出了与算法相关的性能仿真结果。仿真结果展示了CMA均衡器可以提供更好的BER性能及比Sato和DD均衡器更快的收敛速度。
In this paper, the signal model for baseband equalized communication system is addressed, and then three typical Bussgang equalizers based on this model are studied, including constant modulus algorithm （CMA）, Sato and Decision-Directed （DD）. The simulation of the performance related to the algorithm is described. The simulation results show that the equalizer based on CMA could offer better BER performances and much faster convergence speed than those equalizers based on Sato and DD.
