Continuous phase modulation for future satellite communication systems in Ka band

In this paper, a CPM (continuous phase modulation) based waveform is proposed. CPM is an efficient waveform for future satellite communication systems. It yields good power and spectral performance and provides a constant envelope signal. This class of modulation yields a constant envelope signal so that SSPA (solid state power amplifier) terminal amplifier can operate near saturation. These systems operate in Ka-band with MF-TDMA access method on the uplink with the requirements of future satellite communication systems. The system will overcome specific difficulties that may affect the quality of service. The brief summary of the main CPM signal properties and the receiver complexity, serially coded CPM with iterative decoding process is presented. Simulation results are presented in the paper such that coding and decoding schemes achieve good power performance.
