Frequency dependent rejection, dB = Power spectral density of the interfering signal, W/Hz S Frequency response of the wanted receiver, relative power fraction = Frequency, Hz f = Frequency offset, Hz. Δf The interfering signal, is modelled as a flat spectrum within the signal bandwidth and a specified S, ACLR curve outside the signal bandwidth. Similarly, the wanted receiver filter response, is F, 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. Table A10-6 provides results for selected separation distances for the various interference scenarios and deployment environments considered here.
