Spatial Modulation(SM)is a novel multi-antenna transmission scheme
which originally constitutes a mapping relation between inputting bits and transmitting antenna.Due to the fact that the Maximum Likelihood(ML)optimal detection algorithm of SM system requires traversing all possible codebook
the algorithm suffers high detection complexity.For this reason
some people have proposed simplified algorithms
such as MF
sphere decoding algorithm.Different from these algorithms
this paper combines EMF algorithm and NMF algorithm.We add candidate set factor Tto effectively balance the system performance and complexity.Simulation results show that when T =4
the improved MF detection algorithm can achieve similar performance as EMF algorithm
