摘要
Abstract
A communication system model is constructed under Rician channel, the performance of serially-concatenated Turbo code is studied and simulated. According to the principle of adaptive filtering, a modified system model is proposed and its performance is also analyzed. Simulation results show that within a certain range of the Rician factor, the system performance can be improved by the modified model of adaptive filtering algorithm and an additional SNR gain about 0. 5dB can be produced.关键词
