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.
