• The phase noise has a significant effect on the M-ary PSK transmission signal, furthermore the higher-order modulation signal can not be recovered in the presence of phase noise. It is important to define exactly what is required in terms of phase noise within a particular system and to avoid expensive over-specification. Based on the analysis of allowable signal-to-noise ratio for phase reference and required phase error variance for M-ray PSK systems relative to a degradation loss objective, the general phase noise allocation method for M-ary PSK satellite communication systems has been proposed in this paper. The phase noise allocation using the proposed method is adopted for M-ary PSK multi-mode satellite communication systems. Using the oscillator phase noise model and the phase noise model of a frequency synthesizer, the required phase noise spectrum distributions are carried out and the validities of the allocated phase noise spectrums are verified by the system simulation.
