CODED OFDM WITH ANTENNA SELECTION BASED ON SUBCARRIER GROUPS

摘要

In this paper, the performance of coded OFDM transmission over multiple antennas using a joint transmit and receive antenna selection is explored. The channel is assumed as a Rayleigh frequency selective fading type and only the receiver is assumed to have perfect channel state information (CSI). The performance of MIMO OFDM system using pragmatic coding techniques such as convolutional coding (CC), space-time block coding (STBC) and space-time trellis coding (STTC) with antenna selection based on subcarrier groups and other types such as all-tone, per-tone and hybrid techniques are obtained via computer simulations. The results indicatedthat joint antenna selection, particularly based on subcarrier groups, can be a desirable option in Worldwide Interoperability for Microwave Access (WiMAX) and Long Term Evolution (LTE) standards.
