1. A method for constructing at least one Polarization Assisted Convolutional (PAC) code, the method comprising:
passing, by processing circuitry, at least one codeword among a plurality of codewords through a noisy channel to obtain a first bit and a noise value;
determining, by the processing circuitry, whether the first bit is an information bit or a non-information bit based on the noise value by decoding the at least one codeword to obtain at least one decoded codeword;
selecting, by the processing circuitry, at least one of a reward or a penalty for the first bit based on the at least one decoded codeword, the reward being set based on a probability of decoding, and the selecting selects the penalty for the first bit in response to determining the first bit is incorrectly decoded; and
iterating the passing, the determining and the selecting, by the processing circuitry, according to Q-values for each state among a plurality of states, at least one of the Q-values corresponding to the first bit.
