| 摘 要： | 研究了步长对恒模算法（CMA）收敛性能的影响。调整步长至合适的值,使CMA算法性能达到总体最优,并对CMA算法进行改进。仿真结果表明,改进算法与CMA算法相比,收敛速度相近,稳态剩余误差更小,从而解决了CMA算法收敛速度和稳态剩余误差不能同时达到最小的问题。 |

| Abstract: | The effect of step-size λ is studied on the convergence performance of constant modulus algorithm（CMA）.λ is adjusted to an appropriate value so that CMA can achieve overall optimal performance.CMA is improved to achieve further optimal results.Simulation results indicate that the improved algorithm has a smaller steady-state residual error than CMA with the same convergence rate.The problem that neither the convergence rate nor the residual error of CMA cannot be minimized at the same time has been solved. |
| Keywords: | blind equalization CMA MSE residual error |
