Eb/N0Ā is closely related to theĀ carrier-to-noise ratioĀ (CNR orĀ C/N), i.e. theĀ signal-to-noise ratioĀ (SNR) of the received signal, after the receiver filter but before detection:
where
- fbĀ is the channel data rate (net bitrate), and
- BĀ is the channel bandwidth
The equivalent expression in logarithmic form (dB):
