Unified Error Probability Analysis of Maximal-Ratio Combining with Antenna Selection in Nakagami Fading Channels

This paper presents the performance analysis of multiple-input multiple-output (MIMO) technique incorporating maximal ratio combining with transmit antenna selection (MRC/TAS) in frequency-flat Nakagami-m fading channel with single infinite series of tabulated function while the fading index is a real value. In this paper, we derived the simple expression of probability density function (pdf) for MRC/TAS (Nt, 1, Nr) scheme. The probability of outage is first evaluated. Finally, the closed-form expressions of bit error probability (BEP) have been evaluated for MRC/TAS by the effective use of pdf.
