A statistical approach to quantifying the EIRP Spectral Density for SOTM terminals

This paper proposes a statistical approach to off-axis EIRP masks, in order to accommodate satellite communications on the move (SOTM) terminals. A ¿statistical mask¿ provides a reference EIRP Spectral Density (ESD) limitation, which can be exceeded with a specified maximum probability. Statistical masks and their implementation approaches are discussed in detail. Simulations are provided to show that the resulting interference is quantifiable and bounded. The statistical mask provides a sound and practical means in controlling interference. This work provides input to the on-going effort of setting emission standards for SOTM by ITU and military standard bodies.
