Abstract:
In Cognitive Radio (CR) networks, estimating the location of primary users can be used to avoid interfering primary users and exploit spatial resources by using some relaying or beamforming schemes. In this paper, we propose an algorithm to find the position of the primary users by exploiting blind source separation techniques. While conventional positioning algorithms proposed for CR networks need to use antenna arrays to estimate the position of more than one primary user, the main advantage of the proposed method is that it can estimate the position of more than one primary user at once, by using only a single antenna. Simulation results confirm the adequacy of the proposed method with an acceptable accuracy compared to conventional positioning techniques.
