ABSTRACT:
A demodulation apparatus and method using a code table that decreases complexity. The demodulation apparatus includes a code table including a plurality of the code words, wherein similar ones of the code words are arranged to be grouped together; and a soft demodulator to calculate probabilities of individual bits that constitute the code words, and to generate a soft demodulation value of the data word.
