TL;DR: A hierarchical MIMO detection technology which combines OSIC with K-Best SE algorithm is proposed and it is demonstrated that this improved algorithm can achieve low and stable computational complexity with a little degradation in performance.
Abstract: Sphere detection and Ordered Successive Interference Cancellation (OSIC) technologies are the most important techniques in multiple input multiple output (MIMO) detection. In this paper, a hierarchical MIMO detection technology which combines OSIC with K-Best SE algorithm is proposed. The proposed algorithm distributes layers into the two detect techniques and adjusts the ratio based on Channel Gain in each SNR level. The K-best improvement to the proposed algorithm can fix the complexity so that the algorithm is convenient for engineering implementation. By simulations in 8 × 8 uncoded MIMO systems with 16 Quadrature Amplitude Modulation (16-QAM), we have demonstrated that this improved algorithm can achieve low and stable computational complexity with a little degradation in performance.
