Abstract :
By exploiting the motion that occurs in mobile communications and using antenna arrays, we propose signal acquisition and beamforming methods that are applicable even in multipath rich environments. It is shown that the time-averaged correlation matrix of the resulting nonstationary signals is resistant to coherent interferences and is particularly useful for subspace methods and beamforming. Examples demonstrating the performance of the proposed methods are also shown
