Combining of Antenna Selection with Adaptive Modulation and Coding in STBC System

In this paper, we investigate a communication strategy combining of transmit antenna selection with adaptive modulation and coding for space-time block coded system. The antenna selection is based on the criterion of maximizing the average spectral efficiency (ASE) of the whole system for a given bit error rate (BER) constraint. In order to enhance system performance, low density parity check codes (LDPC) is employed as the error correcting codes. We assume that the channel state information (CSI) is known at the receiver and the adaptive control signaling can be perfectly fed back to the transmitter. Simulation results show that our proposed scheme provides a well behaved trade-off between the ASE and BER under MIMO environment.
