摘要

在本文中，我们提出了一种帧间可变速率版本的开关分裂矢量量化器(SSVQ)，用于有效编码AMR-WB ISF频谱参数。仿真结果表明，新的ISF编码方案ISF- vr -SSVQ编码器比传统的ISF SSVQ编码性能更好，每帧可以节省1-2比特。

Efficient coding of wideband ISF parameters : Application of variable rate SSVQ scheme

In this paper, we propose an inter-frame variable rate version of the switched split vector quantizer (SSVQ) developed for efficient coding of AMR-WB ISF spectral parameters. Simulation results will show that our new ISF coding scheme, called ISF-VR-SSVQ coder, performs better than the conventional ISF SSVQ and can save 1–2 bits per frame.
