Abstract :
A new adaptive algorithm for blind adaptive beamforming is studied and applied to the problem of array processing in a cellular communication system using AMPS. The method is based on high-order statistics time-domain processing, and seems to be a good compromise in terms of computational complexity between some intensive high resolution subspace methods recently proposed and the simple, but not always satisfactory gradient-based CMA approach
