Application of blind source separation in radio surveillance

How to acquire,separate and identify the radio communication signals quickly and exactly is a bottleneck of modern radio surveillance,and blind source separation(BSS) is suitable for dealing with these problems.The model of the radio surveillance system based on BSS is presented,and two novel applications are discussed,i.e.the direction-of-arrival(DoA) estimation and modulation identification.Simulation results show that the BSS solution in radio surveillance is valid and feasible.
