<p>PURPOSE: A demodulating and decoding system in a receiver is provided to insert an LLR(Log Likelihood Ratio) value produced by a BCJR(Bahl, Cocke, Jelinek and Raviv) algorithm in a prior demodulating and decoding process. CONSTITUTION: A demodulating and decoding system(100) in a receiver includes a symbol detection unit(110), an LLR(Log Likelihood Ratio) operation unit(120), and a decoding unit(130). The symbol detection unit detects a symbol from first receiving data. The LLR operation unit computes a first LLR value through the detected symbol. According to the computed first LLR value, the decoding unit decodes the first receiving data.</p> |
