摘要：Summary In this paper, multiple-input multiple-output (MIMO) system performance is evaluated over composite Weibull–Gamma (WG) fading channel using antenna selection (AS) techniques. WG fading channel is considered to model multipath and shadowing effects. The capacity and error rate performance can be improved by exploiting channel state information on the transmitter side (CSIT) while reducing hardware complexity. Therefore, AS techniques are used to exploit CSIT. Although, optimal AS improves the system performance at the cost of enhanced complexity, sub-optimal AS technique is preferred to improve capacity performance with reduced complexity level. Also, AS is used for orthogonal space time block code (OSTBC) to improve error performance of MIMO system over WG fading channel.
