      N0 is the noise power spectral density in Watts/Hz. P0 is the signal power at the input of the receiver. If the channel is thermal noise limited, then N0 is equal to the product kT, where T is temperature and k is Boltzmann’s constant. The ratio Eb/N0 is referred to as the SNR-per-bit and the ratio R/B is a measure of spectral efficiency in ...
