| Title: | Novel Codec Structures for Noise Feedback Coding of Speech | ||
| Authors: | Juin-Hwey Chen, Broadcom Corporation, United States | ||
| Abstract: | This paper presents several novel codec structures for Noise Feedback Coding (NFC) incorporating both long-term and short-term noise spectral shaping, as well as long-term and short-term prediction. In addition, the paper generalizes the conventional scalar-quantization-based NFC to vector-quantization-based NFC, and it lays the foundation for the associated efficient VQ codebook search and closed-loop VQ codebook design. BroadVoice®16, a PacketCable 1.5 mandatory narrowband speech codec standardized by CableLabs® for Voice over Cable in North America, is based on one of such novel NFC codec structures. | ||
