Performance comparison of convolutional and turbo convolutional codes for ISDB-T in AWGN and Brazilian channels
This work intends to demonstrate the improvements applied in the integrated system digital broadcasting-terrestrial (ISDB-T). The turbo processing has been considered one of the most promising techniques for the improvement of performance in communication systems. The use of turbo convolutional codes (TCCs) combined with soft decision demapping is proposed for reduction of signal to noise rate (SNR) threshold at reception. Some simulations are done using AWGN and typical multipath Brazilian channels. Therefore, it is concluded that the proposed Turbo ISDB-T performance is better than the conventional ISDB-T in those cases.
