Abstract	This paper investigates the performance of maximum-ratio combining (MRC) linear receivers in a massive multiple-input multiple-output (mMIMO) uplink communication system, that in terms of their signal-to-interference-plus-noise ratio (SINR) operating under independent flat Weibull multipath fading channels (WFCs). Based on a tight approximate probability density function (PDF) expression of the signal-to-noise ratio at the considered receiver output, we derive new accurate closed-form expressions of PDF, outage probability (OP) for mMIMO employing MRC technique. The results show high accuracy for significant values of K×Nr mMIMO system at high/low transmission power and severity fading parameters as well. Indeed, the greater K×Nr, the better the PDF's accuracy, therefore, the better is the OP. Numerical outcomes have been assessed by using Mathematica Software to show up our results. © 2021 IEEE.
