Additive white Gaussian noise (AWGN) is utilized as a variation attribution for various procedures which may be random. It can be added with various noises to make the framework natural. Rayleigh fading is utilized to demonstrate the engendering model which can represent nonlinearity and scrambling. This major combination can be more successful when it can be tried with various adjustments in modulation. It is additionally compelling for the noise reduction. The data transmission with orthogonal frequency division multiplexing (OFDM) and multiple inputs and multiple outputs (MIMO) will be effective in the conjunction of AWGN and Rayleigh fading channel. This paper focuses on various attributes which can reduce the error rates with the help of bit error rate (BER).
