what the different between SNR and CNR?it is better to give some reference, thanks!
 

snr and cnr

SNR = signal to noise ratio, this is computed over a large bandwidth for example, CDMA signal power to noise power
CNR = Carrier to noise ratio, Ideally computed over a Hz bandwidth. The carrier power is used.

Usually CNR =SNR + 10log(BW) for obvious reasons
 

cnr snr eb

what's more, what's difference between SNR and Eb/N0??
