We investigate the symbol error rate (SER) of a transmit antenna selection (TAS)-maximal ratio combining (MRC) with relay and user selection in multiple-input multiple-output systems over non-identical Nakagami fading channels.… Click to show full abstract
We investigate the symbol error rate (SER) of a transmit antenna selection (TAS)-maximal ratio combining (MRC) with relay and user selection in multiple-input multiple-output systems over non-identical Nakagami fading channels. This letter derives the exact cumulative density function (cdf) of the effective signal-to-noise ratio for the proposed system. Using the cdf, this letter derives the exact closed-form expressions of the TAS-MRC with relay and user selection for the SER with M-ary quadrature amplitude modulation over non-identical Nakagami fading channels including quantification of the diversity order using asymptotic analysis.
