Abstract

We present a general framework for studying a lattice construction approach, namely the elementary divisor construction (EDC), which shows its strength in improving the overall rate over the multiple access channels (MAC) with low computational cost. Then a soft detector is developed for lattice network relaying, based on the multilevel structure of EDC. This makes it possible to employ iterative decoding in lattice network coding, and hence to improve the reliability of decoding the linear combinations over the message space.
