| 摘 要： | 以提高通信信号质量和降低其受多径效应的影响为背景,介绍了恒模算法(CMA)及构造函数算法(CF算法),并在此基础上针对其不足作了相应的改进,提出分数间隔修正构造函数盲均衡算法(FSE-MCF)。对改进算法的均衡性能进行了仿真,仿真结果分析可知,新算法与CF算法相比较,在相同信噪比条件下可以进一步减小稳态误差,加快收敛速度,有较好的均衡性能。

| Abstract: | Under the application background of improving the signal quality of communications and reducing the multipath effect,firstly,the constant modulus algorithm(CMA)and construction function algorithm(CF)are introduced,and based on this the corresponding improvement is put forward.Then a new algorithm of fractionally spaced equalization-modified construction function(FSE-MCF)is proposed.The capability of this algorithm is simulated and analyzed.Compared with the CF algorithm,the new algorithm can further reduce the residual error,improve the convergence speed effectively,and has better performance. |
