Development of Fading Channel Modeling Performance for Wireless Channel

Abstract

Fading channel modelling is commonly defined as the variation of a signal's attenuation with various variables.Included are the time, geographical location, and radio frequency. Fading is frequently shown as a random process. As a result, a fading channel is a communication channel that fades. Rayleigh fading channel reflects the fading is caused by multipath reception.  The suggested method in this research uses Rayleigh channels to create a new design and simulate a wireless channel. In order to quantify some path space loss efforts and analyse the performance of different wireless fading channel modelling, Rayleigh channels were used with two approaches (flat and frequency-selective fading channels). The results reveal that when the signal to noise ratio (SNR) is equivalent to 45dB, the biting error rate (BER) performance improves considerably. Finally, the experimental findings reveal that the suggested strategy improves fading channel modelling performance by lowering the BER error when the SNR is dropped. Furthermore, the Rayleigh model is a more precise model that can be used to construct a fading channel model.
