ADAPTIVE TRANSMISSION SIGNAL DETECTION METHOD FOR DECODING MULTIPLE STREAMS CAPABLE OF RESTORING A TRANSMISSION SIGNAL VECTOR BY DETECTING A MAXIMUM LIKELIHOOD POINT WITHIN EACH ALLOCATION SPACE

摘要

PURPOSE: An adaptive transmission signal detection method for decoding multiple streams is provided to effectively detect transmission signals by controlling calculation rates of a sphere decoder.;CONSTITUTION: A reception apparatus receives a reception signal vector(S100). The reception apparatus estimates channel matrix(S110). The reception apparatus decomposes QR(Quick Response)(S120). The reception apparatus calculates initial radius(S130). The reception apparatus calculates a plurality of space divisions of dimensional(S140).The reception apparatus detects an ML(Maximum Likehood) point within each allocation space(S150). The reception apparatus restores a transmission signal vector(S160).;COPYRIGHT KIPO 2012
