Abstract :
This paper presents the phase noise allocation for the digital satellite broadcasting system adopting the QPSK coherent demodulation scheme. The phase noise requirement for the local oscillator of the Korean digital DBS system is 23.7 dB (0.2 dB impairment). To meet this requirement, the local oscillator SNR of the receiver terminal should be 24.12 dB, and 34.12 dB for the transmitter terminal. These phase noise characteristics are applicable to the design of the digital satellite broadcasting system as requirements of the system phase noise
