发明名称 Wideband speech coding system and method
摘要 A speech encoder/decoder for wideband speech with a partitioning of wideband into lowband and highband, convenient coding of the lowband, and LP excited by noise plus some periodicity for the highband. The embedded lowband may be extracted for a lower bit rate decoder. Additionally, the use of a single quantizer for both lowband and highband parts of a wideband codec is disclosed.
