In this paper, we propose a low complexity group detection using higher order multiple input multiple output (MIMO) decoder. As the MIMO system order increases, a higher order MIMO decoder which achieves a good tradeoff between detection performance and algorithm complexity is demanded. However, there is no higher order MIMO decoder which satisfies the good tradeoff balance. Therefore, we propose a good tradeoff balance using higher order MIMO decoder. In the MIMO wireless LAN multipath environment, the complexity of the proposed algorithm is 14.29 % of the conventional one with only a slight SNR performance degradation. The proposed algorithm is applicable up to 8×8 MIMO decoder.
