Split vector quantization of signals in multiple transform domains with application to speech
Wasfy B. Mikhael, Venkatesh Krishnan · 2002
A novel multiple transform split vector quantization (MTSVQ) scheme where each signal vector is projected into multiple transform domains is proposed. For a given transform domains representation, a codebook is designed for each equal energy subband. The coder selects codes from the domain that best represents the signal vector. Sample results using one dimensional speech signals confirm the superior performance of the proposed MTSVQ scheme.
