Abstract
The work addresses the following two problems in conjunction with a shaped constellation: (i) constellation shaping as a means of spectral shaping, (ii) optimum addressing to minimize the effect of channel errors on the end-to-end source distortion. These are expressed in terms of two constrained optimization procedures
