Fast Radix-32 Approximate DFTs for 1024-Beam Digital RF Beamforming
A. Madanayake, R. J. Cintra, N. Akram +6
The discrete Fourier transform (DFT) is widely employed for multi-beam digital beamforming. The DFT can be efficiently implemented through the use of fast Fourier transform (FFT) a…
A Class of Low-complexity DCT-like Transforms for Image and Video Coding
T. L. T. da Silveira, D. R. Canterle, D. F. G. Coelho +3
The discrete cosine transform (DCT) is a relevant tool in signal processing applications, mainly known for its good decorrelation properties. Current image and video coding standar…
Energy-efficient 8-point DCT Approximations: Theory and Hardware Architectures
R. J. Cintra, F. M. Bayer, V. A. Coutinho +2
Due to its remarkable energy compaction properties, the discrete cosine transform (DCT) is employed in a multitude of compression standards, such as JPEG and H.265/HEVC. Several lo…
