基于LMS算法的混合干扰对消模块的设计与分析
Design and analysis of LMS interference cancellation module in eliminating mixed-noise interference
摘要
Abstract
In order to solve many types of interference in wireless communication, three pairs of cancellation module is designed and simulated.First, the principle of LMS adaptive interference cancellation and periodic disturbances separation is described and ana-lyzed, then the conclusion that the effect of the adaptive canceller is related to the order and step-size of LMS adaptive filter closely and the auto correlation matrix of the input directly determines the set of filter parameters is got.Then, the model is implemented on simulink, confirming the effectiveness and feasibility of the module. Finally, the performance of the module is analyzed at different SINR, getting the conclusion that the performance of the module at lower SINR is better than that at higher SINR.关键词
