Abstract:
1. A multiple antenna receiver comprising: a plurality of antennas to receive a plurality of received symbols; a QR decomposition unit to perform QR decomposition for a channel matrix to calculate a Q matrix and an R matrix; a Q-received symbol generator to generate Q-received symbols corresponding to the plurality of antennas based on the plurality of received symbols and the Q matrix; a subtractor to remove a component corresponding to at least one neighbor symbol from a target received symbol corresponding to one of the Q-received symbols; an adder to add a signal component to the target received symbol so that a variation of the at least one neighbor symbol in a frequency domain is equal to a variation of the target received symbol in the frequency domain; a first frequency domain equalizer to perform frequency domain equalization for an output of the subtractor; and a second frequency domain equalizer to perform frequency domain equalization for an output of the adder.
