Efficient Hybrid VLSI Architecture Using Hadamard Transform
The Hadamard Transform (HT) is one of the frequently encountered Discrete Orthogonal Transforms (DOT). It belongs to the class of rectangular real-valued DOT, which can be used for various basic Digital Signal Processing (DSP) operations including the computation of the Discrete Fourier Transform (DFT), implementation of digital filters and spectral estimation. It is considered as an important tool for speech processing and error control coding. Not only is it used frequently for audio and video processing, but also have a lot of other applications in signal and image processing.
