摘要：
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 Korean digital DBS system is 23.7dB (0.2dB impairment). To meet this requirement, the local oscillator SNR of the receiver terminal should be 24.12dB, and 34.12dB for the transmitter terminal. These phase noise characteristics will be applicable to the design of the digital satellite broadcasting system as requirements of system phase noise.
