An innovative low-power high-performance programmable signal processor for digital communications

Journal Article IBM J. Res. Dev. (USA) · 2003 We describe an innovative, low-power, high-performance, programmable signal processor (DSP) for digital communications. The architecture of this processor is characterized by its explicit design for low-power implementations, its innovative ability to join ... Cite

Comments on “On the design of pole-zero approximations using a logarithmic error measure”

Journal Article IEEE Trans. Signal Process. (USA) · 1996 The present paper comments on a paper by Blommer and Wakefield (IEEE Trans. Signal Processing, vol.42, no.11, p.3245-8, 1994 Nov.). The present author shows that the log spectral matching technique described in Blommer and Wakefield is equivalent to least- ... Full text Link to item Cite

Multirate subband coding applied to digital speech interpolation

Journal Article IEEE Trans. Acoust. Speech Signal Process. (USA) · 1987 A statistical analysis is presented of a digital speech interpolation (DSI) system using multirate subband coding. The authors estimate the level of speech quality and grade of service that can be provided by such a system, given values of various system p ... Cite
