Good B) Affected by own ships AIS transmissions, but may be protected from ships own voice communication through filtering. Annex 2 Study from China for channel plan D 1 Task goal The goals of the task are as follows: Compatibility analysis between VDE and ASM, between VDE and voice, and between – different VDE systems. Calculation and simulation of needed isolation space between antennas of VDE and ASM – or voice applications subject to implement of compatibility. 2 Task condition The main condition and input parameter of the task is as following: 1) VDE channel: be consistent with Recommendation Annex 3, or Annex 4: The class of emission: 50K0F1DDN (Annex 3), or 100K0F1DDN (Annex 4). – Modulation: 16 × 16-QAM (Annex 3), or 32 × 16-QAM (Annex 4). – The carrier power: 50 W (coast station transmitters), 25 W (ship station transmitters). – The adjacent channel selectivity: at least dB. – The spurious response rejection ratio: at least 70 dB. – The radio-frequency intermodulation rejection ratio: at least 70 dB. –
