Systems and methods are provided for determining a successive interference cancellation (SIC) decoding ordering in a multiple input multiple output transmission (MIMO) system with retransmissions. A plurality of codewords is transmitted in a current transmission time. Some of the codewords may have been previously transmitted in previous transmission attempts according to a retransmission protocol. The plurality of codewords is received and an ordering metric is computed for a received codeword based on channels associated with multiple transmission attempts of the codeword. A decoding ordering of the codewords is determined based on the computed ordering metric. Performance parameters such as Packet Error Rate (PER), channel gain, and/or equalizer-output Signal-to-Interference and Noise Ratio (SINR) may be used to evaluate a channel quality for each one of the transmission attempts of the codeword. The ordering metric may be updated recursively with each transmission attempt.
