摘要：
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.
