In this paper, we investigate combining single transmit antenna selection (TAS) and receiver maximal ratio combining (MRC) based Multiple-Input-Multiple-Output (MIMO) systems over independent flat Weibull fading channels. In this system, a single transmit antenna, which maximizes the total received signal power at the receiver, is selected for uncoded transmission and is applied to reduce the system complexity without any loss in diversity. Since much research has been conducted on system performance under Rayleigh and Nakagami-m fading channels, this study will focus on new simple approximate closed-form of the post-processing signal to noise ratio (SNR) probability density function (PDF) over Weibull multipath fading channels. Based on this expression, approximate analytical expressions such outage probability (OP), the average channel capacity (CC), and the average symbol error rate (ASER) for several Mary modulation techniques are derived as infinite series, which converge by using a particular hypergeometric function, known as Meijer G-function. Theoritical analysis is verified by computed simulations using Mathematica software. © 2016 IEEE.
