  Abstract

In this letter, a selective symbol-level combining scheme is proposed for MIMO systems with LDPC coded HARQ. Considering bit nodes with a higher degree can affect the decoding convergence more than those with a lower degree during the iterative decoding process, the proposed scheme performs the selective symbol-level combining for the signals having the bit nodes with higher degrees. Simulation results show that the proposed scheme can obtain a better decoding performance than the other selective symbol-level combining scheme of different selection criteria with the identical computational complexity.
