Efficient BER performance analysis in AWGN and Rayleigh Fading Channel with range modulation

In this paper we have proposed an efficient multiple Additive white Gaussian noise (AWGN) and Rayleigh Fading Channel which will be able to 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. We have considered timing error with respect to the timing jitters which is being considered as mismatch of sampling time between the transmitters and receiver may degrades the performance of the system as timing destroys orthogonally among sub-carriers. At the initial stage, we have configured the modulation format to be different for the high spectral efficiency and define the upper and lower limits of the BER threshold. So that different range of Quadrature amplitude modulation (QAM) with quadrature components can be considered. So that the variation is wide for checking the performance.
