A Comparative Study between Multipath Fading Channels

  Ms.Arfiya S.Pathan,  Mr.Abhay Satmohankar

There are various kinds of channel used in wireless communication. This Paper shows a performance analysis on the basis of different fading channels. This is the comparative analysis with different kinds of modulation techniques. We have proposed multipath fading channel simulation model for wireless communication. The effects of noise on fading and property of the channel were tested. Here we have also measured the Bit Error Rate with respect to different modulation techniques and compare the rate in different channels. The results show that the BER performance is improved dramatically in low SNR than in high SNR. This is reasonable since at low SNR, white Gaussian noise dominate the BER error which can be improved by enhancing SNR while in high SNR, phase estimation error dominate the BER error which cannot be improved simply enhancing SNR. Next we have tested, analyzed and compared the performance of the channels. The more accurate model is Rayleigh model which can be considered for developing multipath fading channel model.
