Dummy Based Blind Beam Acquisition and Switching Strategy for DVB-S2X Applications in LEO Satellite Environments

This paper proposes a blind beam acquisition and switching strategy for DVB-S2(X) applications in low earth orbit satellite systems. No position, location and orientation information are required. The algorithm uses regular dummy frames to estimate the best-suited antenna beam iteratively from a candidate list. The best beam pair is determined based on carrier-to-noise estimation. We describe in detail which extensions are needed in the DVB-S2(X) receiver and what challenges have to be solved by the transmitter and receiver. Furthermore, we show FPGA simulation results of the implemented algorithm.
