- W2373300017 abstract "This paper studied the optimal power allocation problem of non-authorized user(NU)in broadband cognitive radio networks based on single-carrier frequency division multiple access(SC-FDMA).Firstly,we introduced the NU to authorized user(AU)interference power models of broadband cognitive radio networks based on SC-FDMA.On this basis,using convex optimization theory in the following two constraints,we derived two kinds of the optimal power allocation(OPA)algorithms to make the sum of rate of NU largest respectively.One constraint is any subcarrier's interference power constraints(IPCs)of any NU to AU.The other constraint is all NU's all subcarriers' interference power constraints(IPC)to AU.Simulation results show that compared with equal power allocation(EPA)and the traditional optimal power allocation(C-OPA)algorithm,the proposed algorithm significantly improves the achievable sum rate of NU." @default.
