Pitch adaptive windows for improved excitation coding in low-rate CELP coders
TL;DR: The pitch-adaptive method is adopted in the design of a novel multimode variable-rate speech coder applicable to CDMA-based cellular telephony and yields excellent voice quality and intelligibility at average bit-rates in the range of 2.5-4.0 kbps.

Successive bit‐vector search algorithm for celp vocoders
TL;DR: The proposed bit‐vector search approach, which reduces the complexity of the CELP speech coders in VLSI realization, can be flexibly embedded with a simple RISC processor to achieve a low‐cost speech coder.
