摘要

本文研究了基于决策反馈滤波器的直接序列扩频接收机在窄带干扰和脉冲信道条件下的可扩展性。理论分析和计算机仿真结果表明，脉冲噪声不会影响DFB接收机抑制NBI的良好性能。脉冲噪声对接收机性能的影响可以通过增加总噪声功率来充分表达。

On narrowband interference suppression using DFB filter in DSSS systems under impulsive channel conditions

In this paper the extension analysis of the recently proposed direct sequence spread spectrum (DSSS) receiver using decision feedback filter (DFB) under narrowband interference (NBI) and impulsive channel conditions is presented. The results, obtained by theoretical analysis and computer simulation in term of the output signal to interference ratio (SIR), show that the impulsive noise does not deteriorate the excellent performance of the DFB receiver in the NBI suppression. The impulsive noise influence on the receiver performance can be adequately expressed through the increase of the total noise power.<>
