Abstract

This paper describes the implementation of a real-time encoding/decoding digital system based on the pyramid vector quantization (PVQ) of subband coefficients. The implementation demonstrates a fast-prototyping approach to the design of portable systems, and addresses engineering trade-offs encountered in building a working system. Low power consumption is the most critical performance criterion in this implementation, which dictates both the hardware and software design choices. We conclude with an assessment of the strength and weakness of the chosen approach as well as possible improvements of the system
