The level of interference
due to receiver blocking , i.e. the power captured from the transmissions of the interferer due to selectivity imperfections of the victim’s receiver (Figure 12), is determined using the interferer’s transmit power, the victim link receiver’s blocking performance, the determined by the interferer’s transmit power, the antenna gains and propagation loss, is further decreased due to the receiver blocking performance for a given interferer/victim frequency separation
, antenna gains and propagation loss. Details on the iRSS
blocking calculation are given in
ANNEX 5:.
Note that with from SEAMCAT 5.0.1 onwards, the blocking attenuation is computed at the ILT frequency and that the ILT bandwidth is nowconsidered (see ANNEX 8:). There are 3 ways to calculate the blocking response which are described in more detail in ANNEX 8::
