The booming of user groups challenges the flexibility of satellite communication systems. A unified modulation and demodulation design for satellite communication systems based on a mathematical mapping and basis expansion model is proposed. The phase shift keying, quadrature amplitude modulation and continuous phase modulation are implemented via the setting of two model structures, the mapping table which unifies mapping processes with and without memory, and the basis expansion coefficient matrix which consistently represents different waveforms. Simulations show that the communication performance of the system with unified design equals and even overmatches classical separated systems.
