基于门限的5G空间调制消息传递检测算法
5G spatial modulation message passing detection algorithm based on threshold
摘要
Abstract
In view of the high complexity and low performance in the classical message passing detection algorithms,a spatial modulation information detection algorithm applicable for 5G communication is proposed on the basis of threshold and message passing mechanism.The large-scaled antenna combination is represented in the generalized spatial modulation system by introducing the method of combinatorial mathematical representation.And then,the primary hierarchical message passing detection model is constructed.On this basis,the Euclidean distance of the received signals is determined quickly by setting the threshold,so as to reduce the invalid iteration of the message passing detection algorithm.On the basis of the above,a message passing detection algorithm with lower complexity is schemed.The results of theoretical analysis and experimental simulation show that the threshold-based message passing detection algorithm has higher detection performance and lower computational complexity in comparison with the hierarchical message passing detection algorithm.关键词
