ORTHOTOPE SPHERE DECODING METHOD AND APPARATUS FOR SIGNAL RECONSTRUCTION IN MULTI-INPUT MULTI-OUTPUT ANTENNA SYSTEM

摘要

An orthotope sphere decoding method of a multiple antenna system is disclosed. The method includes performing tree search using a depth-first method by performing an OC-test on the nodes on which the tree search of orthotope sphere decoding will be performed and performing an SC-test on nodes passing the OC-test; and selecting a transmission symbol having a smallest PED value as a final signal as a result of the search.
