1. An electronic device in a wireless communication system, the electronic device comprising:
a multiple-input multiple-output (MIMO) detector configured to generate an output log likelihood ratio (LLR) value based on signals received from a plurality of antennas and a feedback LLR value;
a channel decoder configured to output a channel decoded LLR value through channel decoding and a second operation by using the LLR value of the MIMO detector; and
a feedback compensator configured to generate the feedback LLR value so that the channel decoded LLR value is between an upper threshold and a lower threshold determined based on a bit width of an LLR of the electronic device.
