Enhancement the Time Variation of Channel Gain by Realize Doppler Spectrum Using Filtered White Gaussian Noise (FWGN) Model

Abstract

Multiple factors have a significant role in fading channel models such as temporal complexities, testing BERs (bit error rates)testing, 2nd order statistical values like autocorrelations, LCRs (level crossing rates), AFDs (average fade durations). These factors impact channel behaviourd, fading qualities and performances of communication systems. The focus of this work is modeling based on FGWNs (filtered white Gaussian noises) and frequencies non selective Rayleigh fading channels. For assisting improvedestimationsanddetectionchannelsmany operations are used li8ke enhancement time varying of data over channels, adjust and execute Doppler filter classificationtracking, that can accuratelymonitoring the time-varying network and that grantagood organization of the information and components estimation.Theproblem in thisstudy is to reconstruct a small portion of time-domain informationcodes transmitted through a network with time-varying with an increase in distortion. We design system based on phase and magnitude distribution of a time-varying with different Doppler frequency of the network that can be applied efficiently. Furthermore, the experimental analysis is done based on time domain channel propertiesproduction of a time-varying that consequencebest performance over a considerable area of channel environments.
