A 4X4 MIMO system’s capacity is found by allocating equal power, optimal power using water filling algorithm and plotted the capacity for optimal power allocation, equal power vs SNR using Python ...

Abstract: A fundamental problem in coding theory is the design of an efficient coding scheme that achieves the capacity of the additive white Gaussian (AWGN) channel. In this article, we study a ...

Abstract: This paper studies the effects of multiple access interference (MAI) for ultra wideband (UWB) systems in AWGN and multipath fading channels. Time hopping (TH) and direct sequence (DS) based ...
