Power allocation for cognitive relay systems


In this paper, the power allocation problem for Orthogonal frequency division multiplexing(OFDM)-based relay cognitive radio systems is investigated. An optimization power allocation algorithm is developed. In the algorithm, objective function is studied and simplified. The channel capacity of secondary users is maximized while keeping the total… (More)
