中文摘要	The demapping method in national standard DTMB system is studied in this paper. A normalization factor a is obtained through statistical approach. Logarithm likelihood ratio basis (LLRB) is calculated by means of formulation. The logarithm likelihood ratio (LLR) is then acquired and sent to LDPC decoder to be decoded. The simulating results show the bit error performance in AWGN channel and GD8 channel, as well as the difference in performance using different quantization bits.
