Abstract :
We studied three types of retransmission scheme for turbo-MIMO packet: Chase combining, soft information combining and incremental redundancy, which are suitable for different situations. The channel in each retransmission is correlated in temporal dimension, the simulation result shows using different interleavers in retransmission is very effective in correlated channel. We also find coding gain of incremental redundancy over Chase combining under most circumstances
