  • It was presented that Turbo trellis coded modulation (Turbo-TCM) scheme and the corresponding decoding algorithm for the system of digital video broadcast (DVB) system where the code rate of the inner error-correcting code was variable. The proposed TTCM scheme employs a simple rate 1/3 binary turbo code, punctured to achieve higher rates. Various code rates and modulation types had been simulated. The proposed turbo trellis coded modulation provides 1~3dB coding gain compared to the convolutional trellis coded modulation scheme used in the European digital video broadcasting standard(ETSI EN 300 744).
