本文提出了一种连续可变斜率增量(CVSD)调制多径搜索编码算法,经过大量的计算机模拟表明,这一算法的性能比CVSD单径搜索编码算法的性能有大的提高,并指出多径搜索编码方法性能稳定,克服了单径搜索编码方案中预测器与粗量化器间的相互作用导致的性能不稳定的缺点。这为研究高效语言编码技术提供了一条途径。
This paper presents a continuous variable slope increment (CVSD) modulation multipath search coding algorithm, after a large number of computer simulations show that the performance of this algorithm than CVSD single-path search coding algorithm performance has greatly improved, and pointed out that more The performance of the path search coding method is stable, which overcomes the shortcoming of unstable performance caused by the interaction between the predictor and the coarse quantizer in the single path search coding scheme. This provides a way to study efficient language coding techniques.
