摘要
针对扩频接收机频域窄带干扰抑制过程中,数据加窗对接收机性能的影响,提出一种稳健的加窗方法——反加窗法。同时,提出了基于反加窗的频域窄带干扰抑制接收机结构。仿真结果证明,该方法能够有效地提高窄带干扰抑制接收机性能。
Aiming to the problem that the performance of spread spectrum receiver degradation due to data windowing in narrow band suppression, a robust windowing technology is proposed in this paper. Furthermore, a novel structure of receiver based on inverse windowing is proposed. The computer simulation results confirm that the novel windowing technology can improve the performance of narrow band suppression receiver.
