Satellite Media Broadcasting with Adaptive Coding and Modulation

Satellite Media Broadcasting with Adaptive Coding and Modulation

Adaptive Coding and Modulation (ACM) is a feature incorporated into the DVB-S2 satellite specification, allowing real-time adaptation of transmission parameters according to the link conditions. Although ACM...
