Abstract: By reformulating the existing radix-2 decimation-in-time (DIT) FHT and complex-valued FFT algorithms using an efficient index mapping, a close relationship between the two algorithms is ...

Abstract: With the rapid development of SAR imaging technology and its expanding applications across missile-borne, airborne and spaceborne platforms, higher requirements were imposed on the real-time ...

Though the FFT algorithm is brilliant---both extremely fast and efficient---it is still limited by the size of the computer's memory. But we can extend the standard Cooley-Tukey algorithm to work on ...

These are the key developments from day 1,462 of Russia’s war on Ukraine.
