摘要
A subband channelizer that includes a demultiplexer that receives input samples of a signal and distributes the input samples to a plurality of channelizer filter banks. A Fourier transform module that receives outputs from the plurality of channelizer filter banks and performs Fourier transformation on each of the outputs of the channelizer filters, and outputs a plurality of Fourier signals. A plurality of multiple modules that receive the Fourier signals, and each of the Fourier signals is multiplied with an exponential value assigned to each of the plurality of multiplier modules to produce oversampled subbands. A combiner for generating a wideband signal from a plurality of input subbands is also included.
