This paper proposes an alternate time-switched transmission technique for orthogonal frequency division multiplexing systems. There are two antennas in the transmitter but it still has only one base-band/RF and a switch that alternates between the antennas at every symbol timing. Alternating transmit symbols result in zeros which make maximal ratio receive combining possible in the receiver. Simulation results show that it has better performance than the traditional algorithm at the expense of one additional antenna.
