요약This paper relates to the soft decision method with erasure technique in digital terrestrial television broadcasting system. The proposed decoder uses the CSI(Channel State Information) derived from using the pilots in receiver. The active real and imaginary data are transferred to the branch metric calculation block that decides the euclidean distance for the soft decision decoding and also the estimated CSI values are delivered to the same block. After calculating the euclidean distances for the soft decision decoding, the euclidean distances of branch metric are multiplied by CSI. To do so, new branch metric values that consider each carrier state information are obtained. We simulated this method in Rayleigh fading defined in ETSI standard[1]. From the simulation, we obtained the results that this method has the better performance of about 0.15 dB to 0.7dB and 2.2 dB to 2.9 dB in Rayleigh fading channel than that of the conventional soft decision method.
