Performance analysis of transmit antenna selection in Weibull fading channel

Abstract

MIMO systems have been proved to improve communication in wireless systems but with increased system complexity. The increase in complexity is due to the increase in the number of radio frequency chains to be decoded at the receiver end. To try to address the problem of complexity associated with an increase in the number of antennas, antenna selection was proposed. For the purpose of this study transmit antenna selection will be considered. The signal-to-noise ratio (SNR) performance as you increase the number of antennas in the system will be studied. Maximal-ratio-combining (MRC) will be considered as the optimal combining technique at the receiver end. The bit-error-rate (BER) performance for different fading parameters β will be studied. In carrying out all these performance analysis the Weibull fading channel will be considered.
