Reduced delay implementation of fourier transform based channelizers and de-channelizers

Abstract From the Canadian patent

In a wireless telecommunications system data processing delays associated , with digital channelization and de-channelization may be reduced through the use of a technique that involves processing data blocks in conjunction with the transformation of the data blocks by a large Fast Fourier Transform (FFT) , algorithm and makes use of multiple transmission and reception branches. In accordance with this technique, the processing delays associated with the FFT algorithm are minimized, but not to the detriment of other important channelizer/de-channelizer design characteristics such as power consumption, die area and computational complexity.
