摘要

本文研究了窄带干扰下DS-BPSK信号的检测，利用变换域处理对窄带干扰进行检测和去除。接收机通过执行实时傅立叶变换，然后跟踪和去除来拒绝干扰。接下来是逆变换和能量检测。为了进一步提高窄带抗干扰性能，对接收信号进行了时间加权处理。在使用加权和剔除的同时，接收机输出端的干扰功率比不使用加权的系统所能达到的额外降低约12db。

Implementation of a DS-Spread Spectrum Intercept Receiver with an Adaptive Narrow-Band Interference Exciser using Transform Domain Processing and Time Weighting

This paper describes detection of DS-BPSK signals in the presence of narrowband interference (CW) where transform domain processing is employed for detection and excision of the narrowband interference. The receiver rejects the interference by performing a real-time Fourier transformation followed by tracking and excision. This, in turn, is followed by inverse transformation and energy detection. To further improve the narrowband interference excision, the received signal is time weighted. Using weighting together with excision, one obtains about 12 dB additional reduction of the interference power at the output of the receiver over and above what one would achieve by using the system without weighting.
