A modulo-lattice transformation for multiple-access channels
Uri Erez, Ram Zamir · 2008
A simple lemma is derived that allows to transform a general single-user (non-Gaussian, non-additive) continuous-alphabet channel as well as a general multiple-access channel into a modulo-additive noise channel. While in general the transformation is information lossy, it allows to leverage linear coding techniques and capacity results derived for networks comprised of additive Gaussian nodes to more general networks.
