Notes

Interferer/Channel @ BER = 10-3, channel level is +3 dB above the typical sensitivity, the interfering signal is CW; channel signal is

modulated with shaping

Channel/Blocker @ BER = 10-3, channel level is +3 dB above the typical sensitivity, the blocker signal is CW; channel signal is

modulated with shaping
