摘要：
The optimal power allocation strategy of cognitive orthogonal frequency division multiplexing (OFDM) system is studied. In order to limit primary user s outage probability, the optimization is formulated maximizing the capacity of cognitive user under the constraint of outage probability at the primary receiver, and the optimal solution to the problem is obtained by utilizing the Lagrange method. Simulation shows that this scheme can efficiently limit primary user s outage probability to its tolerable range while maximizing secondary user s transmission rate.
