Abstract :
In the conventional space-time coding technique, nT radio frequency (RF) chains are employed to transmit signals simultaneously from nT transmit antennas. A low-complexity transmit diversity scheme with nT=2 transmit antennas is proposed, which employs only one RF chain as well as a low-complexity switch for transmission.
