A Study on ACM for Power and Bandwidth Limited Channel in Satellite Communication System

Abstract

This paper proposes and investigates the use of Adaptive Coding and Modulation (ACM) to maintain high frequency utilization efficiency in accordance with the change of power limits and frequency bandwidth channel limits for the Ka-band high through-put satellite (HTS) system. Improvements in frequency utilization efficiency of the Ka-band satellite channel model have been observed when carrying out ACM using the DVB-S2X modulation scheme and error correcting codes.
