- Abstract:
-
For the resouree alloealion unair problem among the second users in cognilive radio, a resouree al.loeation algorithm based on the fairness of the second users rates is proposed, and it also makes the throughpulmaximum. The algorithm can be divided into two steps, cognitive user subearrier alloeation and subearrierpower alloeation. In the first step, two subearrier alloeation schemes are put forward, and those two schemesalloeate subearriers to cognitive users aeeording to their rates ratio. But, the differenee is that subearriers aredivided into two classes in the seeond scheme, and this scheme improves fairness among the users. In the see.ond step , water-filling algorithm is used to make the throughput maximum. The simulation results show the ef.fectiveness of the proposed algorithm.
