Multiple Transmit Antenna Selection in MIMO-OSTBC System in Nakagami-m Fading Channel

摘要

Transmit Antenna Selection (TAS) is essential part of future wireless systems to reduce the complexity of multiple antenna techniques and to satisfy the need of higher data rates. In this paper, we present TAS technique based on Maximal Ratio Combining (MRC) scheme with multiple antenna selection. The sub optimal antenna selection is carried out for selecting more than one subset of antenna which minimizes the upper bound of pair wise error probability. The performance analysis of the system is carried out under Nakagami- m flat fading channel. The Bit Error Rate (BER) analysis is performed for multiple antenna selection in MIMO-OSTBC system for arbitrary values of ‘m’ in Nakagami- m fading channel.
