利用基于滤波器组的重叠变换抑制扩频通信系统中的时变干扰
Non-stationary interference excision in spread spectrum systems using the filter-bank based lapped transform
摘要
Abstract
Among many transform-domain processing techniques,Lapped transform domain excision is an efficient way for interference suppressing. Because the lapped transform can not provide the information both in time-domain and frequency-domain, it is not suit for non-stationary interference excision. In this paper, the idea of using filter-bank is modified in order to retain the time-domain information of input signal. With the help of the threshold method introduced in this paper,the filter-bank based lapped transform can be efficient in suppressing non-stationary interference. Preliminary simulation results show the validity of our method.关键词
