A survey and analysis of BER over different Gaussian noise
Mukesh Bhaskar and Anil Khandelwal
Abstract
Additive white Gaussian noise (AWGN) is used as a variant attribution for different random process. It can be added with different noise to make the system intrinsic. Rayleigh fading is used to show the propagation model which can represent nonlinearity and scattering. This combination can be more effective when it can be tested with different modulation and amplitude. It is also effective for the noise reduction. So the combined transmission system with orthogonal frequency division multiplexing (OFDM) and multiple inputs and multiple outputs (MIMO) will be effective. So the main focuses of this survey paper is to finding the capability with different modulation and improve the error ration by calculating the impact with the help of bit error rate (BER).
