Abstract
A method of transforming input signals received at N input signal ports to output signals for output at M output signal ports includes generating, from the input signals, first intermediate signals for processing by a fast Fourier transform (FFT), with a predefined number of input ports and output ports corresponding to a size of the FFT; applying the FFT to the first intermediate signals to obtain second intermediate signals; and generating the output signals from the second intermediate signals. The input signal ports are non-uniformly distributed with respect to the input ports in a first signal domain of the input ports; and/or the output signal ports are non-uniformly distributed with respect to the output ports in a second signal domain of the output ports. The disclosure further relates to beamforming networks, reconfigurability in beamforming and beam steering, wideband and narrowband multibeam antenna array devices, FFT processors, programs, and storage media.
