Narrow-Band Interference Suppression in Transform Domain in Tracking and Data Relay Satellite System

Article Preview

Abstract:

This paper use the methods of lapped transform to implement DSSS system narrowband interference suppression in lapped transform domain. Interference suppression in part, by improved median filter algorithm in a treatment process can locate and suppress interference, and it will not be activated in the absence of presence of interference, thus saving processing time. From the results of Matlab simulation, we can see the structure based on the analysis of lapping transform that has good performance in anti-narrowband interference, so it will be widely used in the tracking and relay satellite communications system.
