Multiple Input Multiple output (MIMO) is one of the essential technologies in LTE,and the use of MIMO signal detection requires a reasonable compromise between complexity and detection performance.High detection complexity caused by increasing number of antennas is greatly decreased by applying lattice theory in MIMO detection.There are two typical lattice theories:LLL algorithm and Seysen algorithm.Based on these lattice reduction theories,we introduce OSIC and K-best,and thus propose KLR_OSIC,a new MIMO detection algorithm based on lattice reduction.Compared with the existing detection algorithm based on lattice reduction,our algorithm improves the performance of MIMO detection with a lower calculation complexity.As shown in our simulation,the new algorithm achieves a better performance than the existing algorithms based on lattice reduction,and is closer to ML algorithm.
