Incoherent FSK

Binary incoherent FSK detection protocols can be extended to demand that the energy associated with one tone frequency shall exceed that corresponding to the other tone by a factor other than unity. The resultant error, nonerror and reject probabilities are calculated for the case of a Rayleigh-fading signal amplitude against constant-power Gaussian noise and extended to the case where the RMS noise amplitude is itself subject to Rayleigh fading.
