Title:
METHOD AND DEVICE FOR SIGNAL DETECTION
Document Type and Number:
WIPO Patent Application WO/2017/133408
Kind Code:
A1
Abstract:
A method and a device for signal detection, being used for decreasing the complexity of signal detection and improving the efficiency of signal detection. The signal detection method comprises: first sorting a joint channel estimation matrix of a serving cell and an interfering cell, thereby first performing a traversing search of constellation symbols layer by layer on each transport layer of the serving cell, to determine M constellation symbols reserved in each transport layer of the serving cell, M being a positive integer; and as for each transport layer of the interfering cell, by means of calculating decision amounts in each transport layer respectively corresponding to M constellation symbol combinations composed of the determined constellation symbols reserved in the layer, and performing hard decision on each decision amount, obtaining the M constellation symbols reserved in the layer.
