METHOD FOR REDUCING COMPLEXITY OF MIMO RECEIVER WHICH SHARES PREPROCESSING FILTER IN A GROUP UNIT BY ADAPTIVELY USING COVARIANCE MATRIX

摘要

Disclosed is a method for processing a reception signal, and a MIMO receiver, the method comprising a step in which: a reference resource element (RE) is selected within an RE group that comprises a plurality of REs; generated is a preprocessing filter which will be shared by the plurality of REs in the RE group on the basis of channel information of the reference RE; on the basis of channel information of the plurality of REs other than the reference RE, generated is a covariance matrix with respect to each of the REs other than the reference RE; and reception signals with respect to each of the plurality of REs are offset by selectively using the preprocessing filter and the covariance matrix, and thereby detection signals with respect to the RE group are generated.

1. A method of processing received signals at a multiple input multiple output (MIMO) receiver including a plurality of antennas, the method comprising:
selecting a reference resource element (RE) from an RE group including a plurality of REs; generating a preprocessing filter to be shared among the plurality of REs of the RE group based on channel information of the reference RE; generating covariance matrices of the REs except for the reference RE based on channel information of the REs except for the reference RE of the plurality of REs; and generating detection signals of the RE group by compensating for the received signals of the plurality of REs by selectively using the preprocessing filter and the covariance matrices.
