Abstract :
In this document, a novel MIMO HARQ scheme is proposed, which jointly utilizes both chase combining and MLD. By utilizing the bit-wise soft-information (BWSI) derived from channel decoder iteratively for next retransmission´s MLD effectively, the performances, such as PER and throughout seen from simulation results, outperforms conventional HARQ scheme.
