Bidirectional relaying via network coding: Design algorithm and performance evaluation

Research works shed considerable light on the merit of the Physical Layer Network Coding in the Two-Way Relay Channel using lattice codes. This potential is proved under a capacity achieving perspective. However, it is not completely understood if this promised gain is attainable in practical settings. We try in this work to answer to this issue by investigating two network coding strategies: the Compute-and-Forward and the Analog Network Coding. We analyze end-to-end communication using these methods and evaluate their performance in terms of error rate and exchange rate using a low-complexity lattice encoding scheme.
