“…In the later aspect, block Jacket transforms have been tentatively applied to quantum signal processing [10], Big-Data processing [11], emerging new-generation mobile communication, and so on. In addition, new orthogonal transforms, such as complex Hadamard transform [12][13][14], fractional Hadamard or Jacket transforms [15], parametric transforms [16][17][18], hybrid transforms [7], and the generalized orthogonal transforms [14], have been gradually proposed while enriching the orthogonal transform family. Particularly, with advancement of digital systems and widespread availability in the recent few decades, there exist some urgent demands for seeking a scheme to achieve compromise between the generalization efficiencies of Hadamard or Haar transforms and their the extended transforms to adaptively meet the practical implementation requirements.…”
