Resource allocation for cyclic prefixed single-carrier cognitive two-way relay networks

초록

This paper proposes a joint optimization of power allocation and subcarrier pairing for a cyclic prefixed singlecarrier cognitive two-way relay network. The optimal frequencydomain linear equalization receiver and the decision-feedback equalization receiver are considered. Karush-Kunh-Tucker conditions and a dynamic ordering greedy algorithm are applied to efficiently solve the joint optimization problem.
