<p>A 3780-point DFT processor is proposed, which is decomposed into 140 and 27-point DFT modules, and no twiddle factor multiplication is required. The 140-point DFT module is computed using nested WFTA, which includes a pre-add/sub module, a real multiplication module and a post-add/sub module. The 27-point DFT module is constructed by 9 and 3-point WFTA using Cooley-Turkey algorithm.</p> |
