In order to evaluate non-site specific conditions, any specific terrain information is not assumed, but smooth earth surface model is assumed. Furthermore, in the studies, impact of additional clutter losses defined in § 4.5 of Recommendation ITU-R P.452-14 is evaluated. Two interference criteria are used to assess the interference mechanisms of “In-band emissions” from an IMT-Advanced base station to an FSS earth station. Long-term interference criterion: – In-band sharing studies: I/N = 10 dB (T/T = 10%) corresponding to the aggregate interference from co-primary allocation for 20% of any Where N is the clear-sky satellite system noise as described in Recommendation ITU-R S.1432. In the absence of specific recommendations on how to apportion these allowances among the competing potential sources of interference, the long-term interference from any individual secondary or unallocated service as well as interference into adjacent frequency bands (unwanted emissions) should be limited to half of the total noise interference allowance into an FSS link, and from any individual primary service it should be limited to half of the afore mentioned values of 10% of the total noise.

specification does not continue to “roll-off” with additional frequency separation. It can be concluded from Fig. A4-4 that increasing the size of the guard band beyond 20 MHz has no effect on reducing the separation distance required to protect the FSS receiving earth station, i.e. for example if the guard band were to increase from 20 to 100 MHz, the same separation distance would still be required to ensure protect the FSS receiving earth station from harmful interference from IMTA systems.

Frequency dependent rejection, dB S = Power spectral density of the interfering signal, W/Hz Frequency response of the wanted receiver, relative power fraction f = Frequency, Hz Δf = Frequency offset, Hz. The interfering signal, S, is modelled as a flat spectrum within the signal bandwidth and a specified ACLR curve outside the signal bandwidth. Similarly, the wanted receiver filter response, F, is modelled as a flat response within the receive signal bandwidth and a specified ACS curve outside the signal bandwidth. The following figures show the interfering signal, FSS receiver frequency response, and resulting FDR for each interference scenario considered here. A10-5 Frequency dependent rejection IMT base station into FSS station A10-6 Frequency dependent rejection IMT mobile station into FSS earth station The adjacent channel interference levels and FDR curves computed above are combined to derive the frequency separation (centre-to-centre) necessary to meet the stated protection requirement at various separation distances.
