Performce analysis of QSTBC systems based on transmit antenna selection in correlation channel
In this paper, we derive an expression of the instantaneous signal-to noise ratio (SNR) for 4 transmit antennas and 2 receive antennas quasi-orthogonal space-time block codes (QSTBC) system with Jafarkhani code, which as a criteria of antenna selection in spatial correlated Rayleigh fading channels. Under the condition of the correlation matrix is known, both capacity performance and bit error performance on the QSTBC systems with antenna selection are investigated. Computer simulations results show that channel correlation can degrade the performance of QSTBC communications system. Namely, channel correlation can increase system BER and reduce the capacity of the system.
