Radix-2 Self-Recursive Sparse Factorizations of Delay Vandermonde Matrices for Wideband Multi-Beam Antenna Arrays
S. M. Perera, A. Madanayake, R. J. Cintra
This paper presents a self-contained factorization for the Vandermonde matrices associated with true-time delay based wideband analog multi-beam beamforming using antenna arrays. T…
Efficient and Self-Recursive Delay Vandermonde Algorithm for Multi-Beam Antenna Arrays
S. M. Perera, A. Madanayake, R. J. Cintra
This paper presents a self-contained factorization for the delay Vandermonde matrix (DVM), which is the super class of the discrete Fourier transform, using sparse and companion ma…
Low-complexity Scaling Methods for DCT-II Approximations
D. F. G. Coelho, R. J. Cintra, A. Madanayake +1
This paper introduces a collection of scaling methods for generating -point DCT-II approximations based on -point low-complexity transformations. Such scaling is based on th…
