Abstract
This paper evaluates the performance of AL-FEC LDPC codes for push content applications in wireless unidirectional environments, where there is no return channel from receivers to the sender. The study analyses how AL-FEC codes based on LDPC improve the reliability and quality of content delivery over broadcast and multicast channels such as DVB-T. Results in unidirectional wireless scenarios demonstrate the effectiveness of these codes for mobile TV and content download services, showing improvements in received content quality as a function of the allocated bandwidth.
