Method for processing received signal of mimo receiver

A multiple input multiple output (MIMO) receiver including a plurality of antennas and configured to process signals received via the plurality of antennas, the MIMO receiver comprising:

• a transmitter;
• a receiver;
• and
• a processor connected to the transmitter and the receiver and configured to process the received signals,
• wherein the processor:
• selects a reference resource element (RE) from a resource block (RB) including a plurality of REs,
• generates a common filter to be shared among some or all of the plurality of REs of the RB based on channel information of the reference RE,
• selects a first border RE, at which the number of repetitions of a compensation process of a primary signal generated using the common filter exceeds a threshold while progressing starting from the reference RE along any one of a time or frequency axis direction, and a second border RE, at which the number of repetition of the compensation process of the primary signal generated using the common filter exceeds the threshold while progressing starting from the first border RE along the other of the time or frequency axis direction, from the RB, and
• forms an RE group sharing the common filter based on the first border RE and the second border RE.

A method of processing received signals by a multiple input multiple output (MIMO) receiver including a plurality of antennas, the method comprising:

• selecting a reference resource element (RE) from a resource block (RB) including a plurality of REs;
• generating a common filter to be shared among some or all of the plurality of REs of the RB based on channel information of the reference RE;
• selecting a first border RE located on the same time axis as the reference RE, at which the number of repetitions of a compensation process of a primary signal generated using the common filter exceeds a threshold, and a second border RE located on the same frequency axis as the reference RE, at which the number of repetition of the compensation process of the primary signal generated using the common filter exceeds the threshold, from the RB;
• and
• forming an RE group sharing the common filter based on the first border RE and the second border RE.
