[0013] The technical solution of the present invention will be described in detail below in conjunction with the drawings:
[0014] The detection method of the spatial modulation system of the present invention mainly selects a specific subset of the constellation symbol neighborhood, and then performs the first traversal search, thereby determining the bit information that activates the transmitting antenna or has the minimum ohms based on the selected M minimum Euclidean distance results. The quadrant of the symbol corresponding to the combination of distances is determined to determine the quadrant of the transmitted symbol, and then a second search is performed. The present invention performs the first traversal by selecting a specific subset of the four quadrants, which can reduce the number of possible detection and transmission signals for searching, thereby effectively reducing the detection complexity of the receiver, and obtaining better results in the case of lower comp...
