In this letter, a low complexity decoder for non-binary low-density parity-check (LDPC) codes in a multiple-input and multiple-output (MIMO) channel is proposed employing Quasi-orthogonal space-time block code (QOSTBC). The complexity of the proposed decoding algorithm involved grows linearly with the number of transmit antennas and order of Galois Field.
