Adaptive fuzzy assisted detector under impulsive noise for DVB-T systems

Abstract

The main novel contribution of this paper is the improvement achieved on the Digital Video Broadcasting Terrestrial (DVB-T) system by the addition of a fuzzy median filter to reduce the effect of impulsive components. The proposed detector includes the fuzzy median filter and can be adaptively adjusted according to the noise level and type of the noise. The system is studied under Gaussian and impulsive noise. Simulation results show that fuzzy assisted detector reduces the effect of impulsive noise and improves the performance of the system significantly while also working efficiently in Gaussian noise.
