Abstract: An exemplary embodiment of the present invention provides a method for a communication apparatus to process a signal. A first processor of the communication apparatus performs symbol mapping on a first baseband signal transmitted via a PDSCH (physical downlink shared channel). The first processor sends the mapped first baseband signal to a second processor of the communication apparatus by interfacing with the second processor. The second processor modulates the sent first baseband signal. The second processor converts the modulated first baseband signal into an intermediate frequency signal.

Abstract: An operation method of a first communication node in a communication system includes receiving a signal from a second communication node; demodulating the signal to obtain LLR values; calculating a first codeword based on the LLR values; selecting error patterns from among all error patterns based on Hamming weights; generating second codewords by applying the first codeword to each of the selected error patterns; and determining a codeword having a highest similarity to the first codeword among the second codewords as an optimal codeword.
