Method and apparatus for receiving signals in MIMO system

摘要

A MIMO receiving apparatus includes a detection priority decision unit, which receives, via N antennas, signals transmitted from M transmitting antennas and determines the detection priorities of the signals; and a signal detector, which successively detects the signals in a decreasing order from a signal having a higher priority according to the detection priorities determined by the detection priority decision unit. System complexity can be reduced by minimizing the number of the inverse matrix calculations required for an SIC mechanism using one MIMO DFE and MISO DFEs corresponding to the number of transmitting antennas.
