Multi-beam 4 GHz Microwave Apertures Using Current-Mode DFT Approximation on 65 nm CMOS
V. Ariyarathna, S. Kulasekera, A. Madanayake +4
A current-mode CMOS design is proposed for realizing receive mode multi-beams in the analog domain using a novel DFT approximation. High-bandwidth CMOS RF transistors are employed…
A Discrete Tchebichef Transform Approximation for Image and Video Coding
P. A. M. Oliveira, R. J. Cintra, F. M. Bayer +2
In this paper, we introduce a low-complexity approximation for the discrete Tchebichef transform (DTT). The proposed forward and inverse transforms are multiplication-free and requ…
Improved 8-point Approximate DCT for Image and Video Compression Requiring Only 14 Additions
U. S. Potluri, A. Madanayake, R. J. Cintra +3
Video processing systems such as HEVC requiring low energy consumption needed for the multimedia market has lead to extensive development in fast algorithms for the efficient appro…
Multi-Beam RF Aperture Using Multiplierless FFT Approximation
D. Suarez, R. J. Cintra, F. M. Bayer +3
Multiple independent radio frequency (RF) beams find applications in communications, radio astronomy, radar, and microwave imaging. An -point FFT applied spatially across an arr…
