Space time coded OFDM system with transmit and receive antenna selection 

Cinar, Sayat; Güçlüoǧlu, Tansal; Çelebi, Mehmet Ertuǧrul (2010)
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 ...
