    • A system and method for associating Signaling System 7 logical circuits and bearer channels are presented. The system may include an event detector configured to receive an SS7 signaling message on an SS7 signaling link, parse a logical circuit from the SS7 signaling message, receive an SS7 bearer channel, and detect a bearer channel event on the SS7 bearer channel. A statistical learning model block is configured to calculate a correlation confidence value between said bearer channel and said logical circuit. The method may include parsing a logical circuit ID from a signaling message on an SS7 signal link, identifying a bearer channel associated with a bearer event on a bearer circuit, and calculating a current correlation confidence value between the logical circuit ID and the bearer channel.
    • 提出了一种用于关联信令系统7逻辑电路和承载信道的系统和方法。 系统可以包括事件检测器,其被配置为在SS7信令链路上接收SS7信令消息,从SS7信令消息解析逻辑电路,接收SS7承载信道,并检测SS7承载信道上的承载信道事件。 统计学习模型块被配置为计算所述承载信道和所述逻辑电路之间的相关置信度值。 该方法可以包括从SS7信号链路上的信令消息解析逻辑电路ID,识别与承载电路上的承载事件相关联的承载信道,以及计算逻辑电路ID与承载信道之间的当前相关置信度值。

    • A method and apparatus for reducing the complexity of linear prediction analysis-by synthesis (LPAS) speech coders. The speech coder includes a multi-tap pitch predictor having various parameters and utilizing an adaptive codebook subdivided into at least a first vector codebook and a second vector codebook. The pitch predictor removes certain redundancies in a subject speech signal and vector quantizes the pitch predictor parameters. Further included is a source excitation (fixed) codebook that indicates pulses in the subject speech signal by deriving corresponding vector values. Serial optimization of the adaptive codebook first and then the fixed codebook produces a low complexity LPAS speech coder of the present invention.
    • 一种用于通过综合(LPAS)语音编码器降低线性预测分析的复杂度的方法和装置。 语音编码器包括具有各种参数的多抽头音调预测器,并且利用被分为至少第一矢量码本和第二矢量码本的自适应码本。 音调预测器消除了一个主题语音信号中的某些冗余,而向量量化音调预测参数。 还包括源激励(固定)码本,其通过导出相应的矢量值来指示对象语音信号中的脉冲。 首先对自适应码本进行串行优化,然后固定码本产生本发明的低复杂度LPAS语音编码器。
