WHEN NETWORK CODING AND DIRTY PAPER CODING MEET IN A COOPERATIVE AD HOC NETWORK
Abstract : We develop and analyze new cooperative strategies for ad hoc networks that are more spectrally efficient than classical Decode & Forward (DF) protocols. Using analog network coding, our strategies preserve the practical half-duplex assumption but relax the orthogonality constraint. The introduction of interference due to non-orthogonality is mitigated thanks to precoding, in particular Dirty Paper coding. Combined with smart power allocation, our cooperation strategies allow to save time and lead to a more efficient use of the bandwidth and to improved network throughput with respect to classical Repetition-DF and Parallel-DF.
