This paper focuses on the design and implementation of an Earth station transceiver system that employs an innovative approach combining subcarrier composite Pulse Code Modulation (PCM), Phase Shift ...

Abstract: Two different structures for combining multilevel coding and 8-PSK modulation are proposed. With rather low decoding complexity and short end-to-end delay, surprisingly good performance is ...

Choosing a modulation, QAM, PSK or other is based on two opposite considerations: Spectral Efficiency and Signal to Noise Ratio. A third, non actually technical, point comes from interoperability.
