摘要：
In this paper, we propose a pyramid VQ to quantize the transform coefficients of TCX module for the audio improvement of AMR-WB+ codec. The proposed pyramid VQ is compared to the REs Lattice VQ used in the AMR-WB+ standard codec, demonstrating improvement 4% and 5.7%, respectively, in Mean Squared Error (MSE) and 3.3% and 4.7%, respectively, in Perceptual Evaluation of Audio Quality (PEAQ) by 8-dimensional and 16-dimensional Pyramid VQ.
