In this brief, multi-path delay commutator structures are utilized to improve the throughput rate of radix-2 and radix-4 FFT computation by a factor of 2 to 4. Latency can also be reduced by a factor of 2 to 3. Compared with previous radix-2 and radix-4 FFT structures, the proposed high-throughput FFT with doubled throughput rate requires similar or even less hardware cost. Although split radix FFT design is more hardware efficient, the regular structure of proposed FFT structures are attractive for high throughput FFT design.
