Disclosed herein are a received signal processing method including selecting a reference resource element (RE) from an RE group including a plurality of REs, generating a common filter to be shared among the plurality of REs of the RE group based on channel information of the reference RE, detecting primary signals, from which channel influence is removed, of the plurality of REs by applying the common filter to received signals of the plurality of REs, and generating secondary signals by compensating for primary signals of REs except for the reference RE among the plurality of REs using channel information of the REs, and a multiple input multiple output (MIMO) receiver.
