Abstract
A method for the digital frequencey domain implementation of receiving arrays. The steps of the method are as follows: a discrete time input signal is transformed into its spectral components and the redundant spectral components are removed. Products of the non-redundant spectral components with a scaled set of acquired weights are computed. From the so-computed products a first set of spectral sums is calculated wherefrom a second set of spectral sums is derived. Thereafter, the first and second sets of spectral sums are converted to the discrete time domain thereby obtaining a discrete time output signal. The invention also provides a system having receiving components operating in accordance with the method. In another embodiment the invention also provides a method and system for the digital frequency domain implementation of transmitting arrays.
