摘要： Improved methods for coding an ensemble of pulse vectors utilize statistical models (i.e., probability models) for the ensemble of pulse vectors, to more efficiently code each pulse vector of the ensemble. At least one pulse parameter describing the non-zero pulses of a given pulse vector is coded using the statistical models and the number of non-zero pulse positions for the given pulse vector. In some embodiments, the number of non-zero pulse positions are coded using range coding. The total number of unit magnitude pulses may be coded using conditional (state driven) bitwise arithmetic coding. The non-zero pulse position locations may be coded using adaptive arithmetic coding. The non-zero pulse position magnitudes may be coded using probability-based combinatorial coding, and the corresponding sign information may be coded using bitwise arithmetic coding. Such methods are well suited to coding non-independent-identically-distributed signals, such as coding video information.

摘要翻译：编码脉冲向量集合的改进方法利用用于脉冲向量集合的统计模型（即，概率模型），以更有效地编码集合的每个脉冲向量。描述给定脉冲矢量的非零脉冲的至少一个脉冲参数使用统计模型和给定脉冲向量的非零脉冲位置的数量进行编码。在一些实施例中，使用范围编码对非零脉冲位置的数量进行编码。可以使用条件（状态驱动）按位算术编码对单位幅度脉冲的总数进行编码。可以使用自适应算术编码对非零脉冲位置位置进行编码。可以使用基于概率的组合编码来对非零脉冲位置幅度进行编码，并且可以使用按位运算编码对相应的符号信息进行编码。这样的方法非常适合于编码非独立相同分布的信号，例如编码视频信息。
