In this chapter, we investigate a DVB-RCS2-based satellite communication system consisting of a gateway, a satellite, and a return channel satellite terminal (RCST). We formulate an optimization problem to maximize the transmission rate of the system. To solve the problem, we propose an adaptive coding and modulation (ACM) and power control scheme for return link transmission based on the return channel condition and power headroom of the RCST. Simulation results show that the proposed ACM and power control scheme increases the transmission rate as the transmit power of RCST and satellite increases or the power headroom of RCST increases.
