摘要：

In this paper, we derive expressions for exact, approximate, and asymptotic symbol error rate (SER) of transmit antenna selection with maximal ratio combining (TAS/MRC) multiple input multiple output (MIMO) systems for several modulation schemes. We have assumed independent and identically distributed - mu fading channels. We use a moment generating function (MGF) based approach to derive the expressions of SER. The expression for approximate SER is derived by approximating Q Function as a sum of exponentials. The expressions of SER are in the form of sum of converging infinite series for all values of fading parameters. The analytical expressions derived in this paper are also applicable to the SER performance analysis of TAS with selection combining at receiver (TAS/SC) systems. The analytical results are validated by comparing them with the results of extensive Monte Carlo simulations for different values of fading parameters. Finally, the SER performance of TAS/MRC systems and TAS/SC systems has been compared and superiority of TAS/MRC systems over TAS/SC systems has been demonstrated.
