Dear All,
As I understand the minimum frequency spacing for coherent BFSK is 1/2T which results in minimum shift keying. The maximum bit rate is hence two times the frequency spacing.
For non-coherent BFSK the minimum frequency separation is 1/T which limits the maximum data rate to equal the frequency separation.
Maybe this is a stupid question but does this also hold for M-ary FSK?
For example, is the minimum frequency separation between the carrier frequencies for 4FSK the same as in the case for coherent and non-coherent BFSK?
