Optimal Power Allocation for a Relaying-Based Cognitive Radio Network in a Smart Grid

Optimal Power Allocation for a Relaying-Based Cognitive Radio Network in a Smart Grid

This paper obtains optimal power allocation to the data aggregator units (DAUs) and relays for cognitive wireless networks in a smart grid (SG). Firstly, the mutual interference between the primary user and the DAU are considered, and the expressions of the DAU transmission signal are derived based...
