Abstract:

In this paper performances of wavelet-transform-domain(WTD)adaptive equalizers based on the least-mean￣square(LMS)algorithm are analyzed. The optimum Wiener solution, the condition of convergence, the minimum mean-square-error(MSE)and the steady-state excess MSE of the WTD adaptive equalizer are obtained. Constant and time-varying convergence factor adaptive algorithms are studied respectively. Computational complexities of WTD LMS equalizers are given. The equalizer in WTD shows much better convergence performance than that of the conventional in time-domain.
