The authors present a nested-lattice encoding and decoding strategy for Compress-and-Forward (CF) relaying. This complements previous work on a nested-lattice encoding and decoding scheme for Decode-and-Forward (DF) relaying, and provides an alternative to random codes for CF relaying which may be a useful coding strategy for larger networks. The proposed nested-lattice CF scheme's utility is demonstrated by using it to cancel interference in a two-hop Gaussian network with a source, a relay and a destination, in which additive interference experienced at the relay and known at the destination (but not the source).
