Orthogonal Designs - Hadamard Matrices, Quadratic Forms and Algebras (Paperback, Softcover reprint of the original 1st ed. 2017)

Orthogonal designs have proved fundamental to constructing code division multiple antenna systems for more efficient mobile communications. Starting with basic theory, this book develops the algebra and combinatorics to create new communications modes. Intended primarily for researchers, it is also useful for graduate students wanting to understand some of the current communications coding theories.
