Efficient Compute-and-Forward Network Codes Search for Two-Way Relay Channel
Lili Wei, Wen Chen · IEEE Communications Letters · 2012
We consider the two-way relay channel (TWRC) with compute-and-forward network coding strategy. First a new lemma is proposed as network codes search criteria for TWRC. Then, instead of exhaustive search, we present an efficient network codes search algorithm based on modified Fincke-Pohst method. Numerical results demonstrate the effectiveness and complexity reduction of our proposed lemma and algorithm.
