Abstract :
In this paper, the outage probability and average bit error rate of a multiuser, multiple input multiple output (MIMO) systems has been incorporated with transmit antenna selection maximal ratio combining (TAS/MRC) over Rayleigh fading channels considering exponential correlation. Exponential correlation is observed when antennas are placed in a linear array in a receiver. A closed form analytical expressions for the outage probability and the ABER for binary modulations have been derived. Outage probability and ABER have been studied for various levels of correlation with different level of diversity order. Finally, obtained analytical expressions have been validated by Monte-Carlo simulation.
