本书是国际上第一本有关高维哈达玛矩阵及其在电信与信息安全领域中的应用专著《Theory and Applications of Higher Dimensional Hadamard Matrices》的修订版，分为三个部分。第一部分重点研究经典的2维Walsh矩阵和哈达玛矩阵，包括它们的快速算法、最新构造法、存在性结果及其一般性的推广。第二部分考虑的是低维情形，例如，3-维、4-维和6-维Walsh和哈达玛矩阵与变换。第三部分是全书的核心也是本书的独特之处，研究了N-维2阶哈达玛矩阵，并证明了这类矩阵与著名的H-布尔函数和2阶最佳二进阵列是等价的，由此，推导出了一系列有关高维2阶哈达玛矩阵的计数结果。本书中还罗列了许多有关高维哈达玛矩阵理论研究和工程应用的公开问题。
