Abstract :

Additive white Gaussian noise (AWGN) is an essential model which is utilized as a part of Information hypothesis to copy the impact of numerous arbitrary procedures that happen in nature. AWGN is frequently utilized as a channel display as a part of which the main debilitation to correspondence is a direct expansion of wideband or background noise a steady phantom thickness The model does not represent blurring, recurrence selectivity, impedance, nonlinearity or scattering. Notwithstanding, it creates straightforward and tractable numerical models which are helpful for picking up knowledge into the basic conduct of a framework before these other phenomena are considered. Rayleigh channel is a measurable model for the impact of an engendering situation on a radio sign, for example, that utilized by remote gadgets. Rayleigh blurring models expect that the extent of a flag that has gone through such a transmission medium (additionally called a correspondences channel) will fluctuate haphazardly, or blur, as indicated by a Rayleigh conveyance the spiral part of the whole of two uncorrelated Gaussian arbitrary variables. In this study we are study the combined effect of this model irrespective of transmission mode like orthogonal frequency division multiplexing (OFDM) and multiple inputs and multiple output (MIMO) system. So that the bit error rates (BER) can be reduced.
