Hello everybody!

I have analysed the immunity of an ASK-, FSK- and PSK-modulated rf-signal to the interference of another ASK-, FSK- and PSK-modulated interfering signal. The most measurement results are clear but there is one issue that I can't find an answer for. When I use an ASK-modulated signal with a bit rate of 50 kBit/s it is less resistant than the same signal with a bit rate of 200 kBit/s. The interfering signal was another ASK-modulated rf-signal (bit rate was also 50 kBit/s and 200 kBit/s, it didn't matter very much).
This confuses me since the receiver sensitivity normally is better when using an ASK-signal with 50 kBit/s instead of a 200 kBit/s ASK-signal (without radio interferers, only white noise).
