AB The  capacity-achieving  input  distribution  of  the complex Gaussian channel with both average- and peak-power constraint  is  known  to  have  a  discrete  amplitude  and  a  continuous,  uniformly-distributed,  phase.  Practical  considerations, however, render the continuous phase inapplicable. This work studies  the  backoff  from  capacity  induced  by  discretizing  the phase  of  the  input  signal.  A  sufficient  condition  on  the  total number  of  quantization  points  that  guarantees  an  arbitrarily small  backoff  is  derived,  and  constellations  that  attain  this guaranteed performance are proposed.
