Abstract
The present invention relates to a signal detection method and a receiving apparatus in a multiple input multiple output (MIMO) system. More particularly, the present invention relates to a signal detection device in a MIMO system using a spatial multiplexing (SM) method. In the signal detection method, a channel is estimated and layers are rearranged according to a predetermined layer arrangement rule. QR-decomposition is performed by using a rearranged system model, all constellation points in a symbol of a layer having the lowest reliability are considered, and symbols are detected by using a sequential interference elimination method.
