RESUMO
The aim of this work is to study the performance of channel encoders with iterative decoder: and also different encoders concatenation schemes to mobile digital television standards ;; DVB-H and ISDB-T. The contribution of this work is a proposal of encoder concatenatic scheme for COFDM systems evaluated through software implementation. The final results I this work presents overall coding gain with respect to digital TV standards. The gain presenb in this work is regarded to the concatenation of BCH encoders with Turbo and LDPC encodel The simulations were performed over multipath, Rayleigh, A WGN and typical Brazili: broadcast channels used for digital TV trials
