Abstract
In accordance with a method for performing frequency subchannelization, a digital signal is received at an original sampling rate. A plurality of multirate frequency channels is produced by dividing the digital signal into an integer number of multirate frequency channels such that a sampling rate of each of the multirate frequency channels is proportional to a center frequency of the frequency channel. Signal processing is performed on each of the multirate frequency channels. The original sampling rate is reconstructed using the multirate frequency channels.
