基于模式搜索的自适应干扰抵消器算法的研究

为了减小同址干扰对接收机性能的影响,设计了一种基于正交矢量合成的自适应干扰抵消器；根据其中控制单元提取出的数据的特点,提出了将模式搜索算法(PSA)作为控制器算法,并对其进行了改进；利用实际测量的数据进行了仿真分析,结果表明,相比于PSA算法、模拟退火算法、遗传算法,改进后的PSA算法具有更快的收敛速度,同时收敛精度相差无几；最终的实现结果也证明了该方法可满足性能要求。

Research of adaptive interference cancellation algorithm based on pattern search

To reduce the influence of cosite interference on the receiver performance, a kind of adaptive interference canceller based on orthogonal vector synthesis is designed. According to the characteristics of extracted data from the control unit, pattern search is proposed as a controller algorithm and improved. Simulation analysis are carried out using actual measurement data. The results show that, compared with the PSA algorithm, simulated annealing algorithm, genetic algorithm, the improved PSA algorithm has faster convergence speed, while convergence accuracy is almost the same. The final implementation results show that this method can meet the performance requirements.
