An SCCC turbo decoder for DVB - T

Abstract—The Digital Video Broadcasting – Terrestrial (DVBT) standard represents the dominant solution for the implementation of digital television in Europe. DVB-T requires error control protection in order to provide the best Quality of Service at the receiver. The current error protection scheme is Reed Solomon coding combined with convolutional encoding. In this paper we propose a new channel coding scheme for DVB-T standard which uses a turbo encoder-decoder with Serial Concatenated Convolutional Codes (SCCC). Our simulation results show that an SCCC turbo encoder-decoder performs better in AWGN channels, gaining about 2.1 dB compared to the standard DVB-T encoding-decoding scheme. Moreover, our results show that the most advantageous choice for the number of iterations of the proposed channel coding scheme seems to be 8, while the best value for the SCCC encoder random interleaver seed is 12000.
