Abstract(in Japanese) (See Japanese page)
Abstract(in English) The convergence property of the Least Mean Squares adaptive array may degrade in mobile communication environments. To avoid this degradation, the authors have proposed two types of new methods. One is "Resetting" in which the weight coefficients are reset periodically and the other is "Bracing" in which the coefficients are slightly shortened at every iteration. It has been already confirmed that both of the proposed methods are fundamentally effective in Rayleigh fading environment. In this paper, the performance of the both methods in Nakagami-Rice fading environment are evaluated. The results of computer simulations show that the Bracing is superior to Resetting in Nakagami-Rice fading environment.
