Abstract	A mixed Fourier-Walsh signal representation is proposed for transform coding. Basis functions from two transforms are used, namely, the Discrete Fourier Transform (DFT) and the Walsh-Hadamard Transform (WHT). An iterative algorithm is employed to implement the mixed representation. A finite number of DFT components is used to represent the selective (narrowband) dominant spectrum of speech on a frame-by-frame basis. The whitened (broadband) residual signal is represented using a small number of Walsh components. The parameters of the mixed representation are coded directly by coding the DFT and WHT components. Results are given for frame-by-frame and packet coding at rates ranging from 16KBPS to 9.6KBPS.
