【摘要】 为了提高对不同窄带干扰的抑制效果,提出一种利用Givens旋转的正交分解的自适应非线性干扰抑制算法.传统Givens旋转算法涉及平方根运算,要消耗较多硬件资源或需要多次循环来实现,为此,提出一种无平方根与除法运算的Givens旋转算法,并结合信号输入矩阵的特殊结构,给出一种低复杂度的干扰抑制算法,将窄带干扰建模为自回归过程以及数字窄带信号.更多还原

【Abstract】 In order to improve the performance of antijamming for various interferences,an adaptive nonlinear algorithm using Givens rotation orthogonal decomposition is developed.The traditional Givens rotation algorithm involves root computation that needs more hardware resources,a Givens rotation algorithm without root and division computation is presented.And,combined with special structure of input signal matrix,a interference suppression algorithm with low computation is proposed.The narrowband interferences are modeled as autoregressive process and digital signal.更多还原
