Abstract :
We consider MIMO-HARQ protocols with/without relay under block fading channels with the assumption that the source, destination, and relay are half-duplex nodes with two antennas. The achievable rate of 2×2 MIMO-HARQ protocols are obtained when the number of retransmissions is unlimited and the optimum ratio between the two streams of two antennas is obtained. The MIMO-HARQ protocol without relay can achieve the ergodic capacity and the proposed MIMO-HARQ protocol with relay is a near capacity approaching scheme.
