A Hardware-Efficient 1200-point FFT Architecture that Combines the Prime Factor and Cooley-Tukey Algorithms

Abstract: In this paper, we present a hardware-efficient 1200-point single-path delay feedback (SDF) fast Fourier transform (FFT) architecture. Contrary to previous FFT architectures for ...

Multiscale Spatial–Frequency-Domain Cross-Transformer for Hyperspectral Image Classification

Abstract: Recently, the Transformer has achieved significant success in the hyperspectral image (HSI) classification task. However, most Transformers and their variants focus more on spatial-domain ...
