Abstract

This paper invests three methods to calculate satellite downlink power flux density (PFD) mask for the new VHF data exchange system (VDES), which aims at providing a wide-bandwidth two-way communications for vessels. Considering Rec. ITU-R M.1808, different protection criteria combined with performance degradation to the land mobile service incumbent is invested by the author. One method is considered on interference to noise ratio, and second method is seminar to method 1 besides the noise floor calculated considering the environment noise floor defined in Rec. ITU-R P.372. And the third method is derived to calculate the carrier to interference and noise ratio. Based on theoretical calculation and simulation, the PFD mask derived from the Carrier-to-Noise plus interference constraint is a more adequate PFD mask for VDES satellite components, which can protect both analog and digital land mobile systems in the same band.
