 During the simulation, some realtime info is shown: ppm value, frequency offset (50PPM --> 122.5KHz under 2.45GHz center frequency of 2.4GHz ISM band), BER and related the number of error bits, etc.

 From the above figure, BER 0.1% is achieved around SNR 13.5dB. In modern hardware, 30PPM is an easy task for a crystal, and it already can bring big gain on the sensitivity.
