Abstract

Ultra Wide Band (UWB) and Cognitive Radio (CR) offer radically different approaches to efficiently use the seemingly scarce spectrum in wireless communications. In this paper, we study the combined cognitive multiuser spectrum sharing and power allocation problem in the context of Multiband OFDM. A proposed gradient power allocation scheme with a target based game strategy is investigated to solve the power control and spectrum allocation problems in a four user coexistence environment. The simulation results illustrate that users can efficiently approximate the predetermined target data rate by means of the proposed game approach.
