Abstract:
1. A receiver of a multi-input multi-output system using multiple antennas, the receiver comprising: a first multiplying unit for multiplying a vector r received via the antenna by a Hermitian matrix Q; a candidate transmitting vector generating unit for detecting a signal on a lowest modulation order transmitting antenna from a received vector y output from the first multiplying unit, creating as many symbol candidates as the modulation order of the detected signal, and generating a candidate transmitting vector using each symbol candidate; a transmitting vector determining unit for obtaining a distance between each candidate transmitting vector generated by the candidate transmitting vector generating unit and the received vector y to determine a final transmitting vector; a demodulating unit for demodulating the transmitting vector determined by the transmitting vector determining unit; and a decision feedback (DF) detecting unit comprising:
