Abstract :
A closed-form expression is derived for the average click rate in an FM system when the transmitted signal experiences Rician fading. Click rate is useful for predicting the bit-error-rate (BER) performance of a digital frequency modulation (FM) signal demodulated by a limiter-discriminator. In the derivations, the assumption is made that the fading is relatively constant over a baud interval (the slow fading case). Also, a definition of the signal-to-noise ratio is used that includes the multipath as a signal component rather than treating it as noise. The validity of the formulae for positive and negative click rates has been verified by experiment
