title = "Robust power allocation for cognitive radio system in underlay mode",
abstract = ". In this paper, the power allocation problem in cognitive underlay system is studied given a number of samples of interference channel{\textquoteright}s gain. System throughput of secondary users is aimed to be maximized while limiting the worst-case interference outage probability. With only a number of samples of interference channel{\textquoteright}s gain, we define an uncertain region of possible probability density function (PDF) of interference channel{\textquoteright}s gain and further derive the closed-form expression for the interference outage probability constraint. By replacing the formulated constraint on interference outage probability with closed-form one, we show the originally formulated problem is a convex optimization problem.",
