Cross – Correlation of the Two FSK Signals.



FREQUENCY SHIFT KEYING - ERROR PROBABILITY:

The Probability of error of an FSK system depends on the separation of “distance” d, between two (or more) signals



The probability of error is minimum when the distance of separation is maximum i.e larger the d, smaller is the P.E.

The distance d is given by:

　　　　d = (1 -  ) / 2

where

　　 = (1 / E) 0 T s0(t) s1(t) dt.

The integral is the cross-correlation function over the period 0 to T.  is restricted to values between +1 and –1.
