| 摘 要： | 针对双门限方法存在的不足,提出一种重叠加窗的双门限窄带干扰抑制方法.该方法在双门限方法的基础上,引入重叠加窗的概念,选取了一种合适的窗函数,对其进行改进.该方法通过重叠加窗,解决了原算法因加窗而带来的时域信号失真问题.仿真结果表明,与原方法相比,该方法在降低误码率的同时也提高了信噪比改善量.

| Abstract: | Based on the shortcomings of the double threshold method,a double threshold method with overlap windowing is proposed in this paper.The proposed method is improved by overlap windowing and choosing appropriate window function on the basis of the original one.It can effectively sovle the problem with overlap windowing that the signal is distorted in the time domain because of windowing.Compared with the former method,its bit error rate(BER) is smaller and the SNR improvement is larger.Computer simulations sh... |
