Abstract :
Signal separation algorithms can be utilized to improve channel capacity of mobile communication systems with frequency re-use. Blind source separation of signals received using circular antenna arrays is compared with that received using linear antenna arrays. Circular antenna arrays can be better concealed than their linear counterpart, and do have a 360 degrees field of view. Techniques for improving the performance of source separation algorithms for circular arrays through interpolation are implemented. The interpolated arrays are proposed as alternative base station receivers for mobile communication systems
