Discrete Pseudo-Fractional Hadamard Transform and its Fast Algorithm

IEEE Signal Processing Letters, 2020
In this paper a new discrete fractional transform for data vectors whose size $N$ is a power of two is proposed. The basic operation of the introduced transform is a discrete fractional Hadamard transform. Since the described transform is not a classical
