This paper describes new efficient Vector Quantization (VQ) techniques that enable low complexity implementations of VQ-based Noise Feedback Coding (NFC). These methods offer mathematical equivalence to higher complexity methods. Furthermore, the paper presents efficient codec structures for general noise shaping as used in BroadVoice 16 - a new SCTE (Society of Cable Telecommunications Engineers) and PacketCable speech coding standard for Cable Telephony.
