窄带多径信号的matlab仿真，Modeling the wireless Propagation channel code-Narrow-band multi-path signals in matlab simulation, Modeling the wireless Propagation channel code

变步长 普通cma在 下的比较， 可见：小步长下，变步长收敛速度比普通cma较慢， -Comparison of CMA with variable step size, Visible: small step length, the convergence rate is slower than ordinary cma,
