The capacity of a Gaussian channel can be achieved if and only if the channel outputs are Gaussian and it has been known since Shannon’s breakthrough paper in 1948. Conventional mapping schemes, like ASK, QAM or PSK suffice for approaching the Shannon limit in the low signal-to-noise ratio (SNR) reg...
