摘要
Abstract
An improved scheme was proposed for pseudo-random noiee code acquisition of DS-SS signals based on adaptive fdters. The system dynamically adjusted the weights of two parallel filters that used different least mean square error algorithms, and achieved faster convergence and a better steady state performance Analysis and simulations demonstrated that the proposed scheme had less acquisition time, and its structure was simple, which can implement easily in hardware.关键词
