An optimized soft-decision de-mapping method for Chinese Terrestrial DTV (Digital TV) Broadcasting Standard is proposed, which can be used on 64QAM, 32QAM, 16QAM and 4QAM de-mapping that compliant with the standard. Using the simplified de-mapping algorithm, the hardware resource usage and working speed are both optimized. Especially for 32QAM mode, comparing to traditional method, 75% hardware resource is saved, and the maximum working speed is 11% faster. The method is already implemented in the Chinese Terrestrial DTV receiver.
