非合作通信中的盲均衡技术研究
Research of blind equalization for non-cooperative communication
摘要
Abstract
A new blind equalization algorithm is proposed for short message detection and reception in non-cooperative communication. Based on the T/4 fractionally-spaced constant modulus algorithm(T/4-FSE-CMA), the new algorithm introduces data reuse method and variable step size idea. Data reusing can sharply reduce the number of symbol that need to converge. Variable step size can further improve the accuracy of the algorithm. Simulation results show, compared with T/4-FSE-CMA and Data Reuse CMA(DR-CMA), the new algorithm has faster convergence speed and higher steady-state accuracy, as well as a lower BER. The new algorithm has great engineering application value.关键词
