本文提出了有限域上的块逆Jacket变换(BIJT)的正交上循环框架。代替传统的块逆Jacket矩阵(BIJM),我们研究了上循环块逆Jacket矩阵(CBIJM),其中高阶CBIJM可以分解为具有连续块结构的低阶稀疏CBIJM。它有一个递归的方式,导致一个快速的算法,以减少计算量。快速变换也开发了二维共循环块逆Jacket变换(CBIJT)。本文提出的CBIJM可用于许多基于矩阵的应用,如DFT信号处理、组合学和Reed-Muller码设计。
AbstractAn orthogonal cocyclic framework of the block-wise inverse Jacket transform (BIJT) is proposed over the finite field. Instead of the conventional block-wise inverse Jacket matrix (BIJM), we investigate the cocyclic block-wise inverse Jacket matrix (CBIJM), where the high-order CBIJM can be factorized into the low-order sparse CBIJMs with a successive block architecture. It has a recursive fashion that leads to a fast algorithm concerned for reducing computational load. The fast transforms are also developed for the two-dimensional cocyclic block-wise inverse Jacket transform (CBIJT). The present CBIJM may be used for many matrix-based applications, such as the DFT signal processing, combinatorics, and the Reed-Muller code design.
