- This paper present the detailed design and the algorithm for forward link ACM(Adaptive Coding & Modulation) system to improve the link availability and system throughput in satellite communication services. To implement ACM system, the channel prediction and MODCOD decision methods is simulated. The channel prediction result shows that the 99% of predicted values in LMS(Least Mean Square) algorithm is within 3dB. Also this paper proposes the appropriate system architecture for ACM transmission. © 2013 IEEE.
