WebAs an example, we can note by using these curves that on a gaussian channel, with a 64-QAM modulation, for a code rate of 2/3, the Shannon limit is E s /N 0 = 12.6 dB. Indeed, a 64-QAM modulation has a maximum capacity of 6, a code rate of 2/3 gives a target spectral efficiency of 4 bits/symb/Hz, and that corresponds to E s / N 0 = 12.6 dB and ... WebAbstract: Shannon's celebrated formula W ln(1 + P o /N o W) for the capacity of a time-continuous communication channel with bandwidth W cps, average signal power P o, and additive Gaussian noise with flat spectral density N o has never been justified by a coding theorem (and “converse”). Such a theorem is necessary to establish W ln(1 + P o /N o …
