METHOD BY WHICH MIMO RECEIVER PROCESSES RECEPTION SIGNAL BY ALIGNING PLURALITY OF LAYERS BY RE GROUP UNIT

摘要

Disclosed is a reception signal processing method of an MIMO receiver, which: determines a detection order, which is the order of processing reception signals received by a plurality of layers through a plurality of antennas, by using channel information of a reference RE; generates a common multi-filter for processing the reception signals according to the detection order; generates an RE group, which includes a plurality of REs and in which the common multi-filter generated on the basis of the reference RE is to be shared; and applies the common multi-filter to each reception signal of the REs excluding the reference RE in the RE group such that detection signals are generated for the plurality of layers from each reception signal of the REs.
