Variable Coding and Modulation (VCM) and Adaptive Coding and Modulation (ACM)

Background

Variable Coding and Modulation (VCM) and Adaptive Coding and Modulation (ACM) are techniques that are strongly associated with the DVB-S2 standard. VCM can be used to provide different levels of error protection to different components within the service.

ACM extends VCM by providing a feedback path from the receiver to the transmitter to allow the level of error protection to be varied dynamically in accordance with varying propagation conditions. Claims of performance improvements exceeding 100% have been made for ACM in terms of satellite capacity gain. (continue reading…)
