Abstract

In this paper, antenna selection both at the transmitter and the receiver is proposed for space-time coded (STC) orthogonal frequency division multiplexing (OFDM) systems. Antennas for all-subcarriers or per-subcarrier are selected to maximize the signal to noise ratio (SNR) at the receiver which knows the channel state information perfectly and the transmitter only knows the indices of the selected antennas. The error performance is evaluated via simulations when space time block and concatenated coding is used. The results indicate that the joint antenna selection can be a highly appealing solution for increasing the performance and reducing the hardware/software complexity in OFDM based systems like WiMAX.
