Implementation of ISDB-T LDM broadcast system using LDPC codes

This paper presents the scenario of terrestrial broadcast services, the challenges and needed adaptations for the next generation television. It shows promising technologies such as LDM, LDPC, NUC and their advantages in terms of increase of transmission rate, robustness and efficient use of spectrum. It also proposes an adapted ISDB-T system that uses LDM, LDPC, NUC and SDR technologies to increase performance and useful bit rate to DTV applications, while using a layer that would still be compatible with traditional ISDB-T system.
