Abstract :
The paper describes a new fast Fourier transform (FFT) algorithm and its implementation. The algorithm is superior to traditional FFT algorithms, requiring fewer computations and having reduced latency. A full set of accurate classical coefficients is calculated at each sample arrival. An 8-point processor was simulated in Matlab. A 64-point ASIC simulation in 0.18 μm CMOS gave results of 16 mW, area = 1 mm2 and sample rate = 2.5 MS/sec when clocked at 330 MHz
