Description: Research on wireless channel optimization problem, since non-deterministic channel matrix rows dissatisfaction rank M MIO system characteristics, resulting in MM SE-GDFE left after pretreatment introduced strong interference, the traditional K-Best algorithm to generate the error floor effect. To eliminate the error floor effect, made part of the maximum likelihood and K- Best combination of algorithms and strong interference detection using part of the initial area of the maximum likelihood algorithm to obtain local optima and reduce the impact of strong interference elimination system error leveling effect, and then use K-Best detection algorithm to complete the remaining symbols on the basis of the local optimal solution to ensure that M MIO soft detector output characteristics. Simulation results show that the algorithm eliminates the error floor effect of traditional K-Best algorithm to ensure the reliability of detection
