Abstract :
Modified sign Haar transform with sign Walsh-like structure is introduced in this article. This nonlinear transform converts binary/ternary vectors into digital spectral domain and is invertible. Recursive definitions for the calculation of this transform have been developed. With its unique and isomorphic properties, this transform is suitable for security coding in a communication system.
