    Abstract: A receiver is used in decoding a received encoded signal. The received encoded speech signal is encoded using excitation linear prediction. The receiver receives the encoded speech signal. The encoded speech signal comprises a code, a pitch lag and a line spectral pair index. An innovation sequence is produced by selecting a code from each of a plurality of codebooks based on the code index. A line spectral pair quantization of a speech signal is determined using the line spectral pair index. A pitch lag is determined using the pitch lag index. A speech signal is reconstructed using the produced innovation sequence, the determined line spectral pair quantization and pitch lag.

    Abstract: The generation of multipulse excitation codes by digitizing an original speech, partitioning the digitized signal into a number of samples, pre-emphasizing the samples, producing linear predictive reflection coefficients from said samples, quantizing these reflection coefficients, converting the quantized reflection coefficients to spectral coefficients and subjecting the spectral coefficients to pitch analysis to obtain a spectral residual signal.

    Abstract: Embodiments herein provide systems and methods tracking the weight of an individual situated on a furnishing such as a chair or bed. One method generally includes receiving weight data at a weight sensor that is situated to recognize a change in weight on the furnishing, determining that a mobile device of the individual is proximately located to the weight sensor, and confirming by the mobile device that the change in weight is related to the individual.

    Abstract: A method and apparatus for processing speech in a wireless communication system uses CELP speech encoded signals. A decoder receives encoded speech including a code index, a code index gain, a pitch lag, a pitch gain, and a line spectral pair (LSP) index. An innovation codevector and an adaptive codevector are determined and scaled. An excitation sequence is generated. Reconstructed speech is then output based on the excitation sequence and LSP index.

    Abstract: A method and apparatus for processing speech in a wireless communication system uses CELP speech encoded signals. A speech input receives samples of a speech signal and a codebook analysis block for selects an index of a code from at least one of a plurality of codebooks. A weighted synthesis filter is used in the generation of a prediction error between a predicted current sample and a current sample of the speech samples. The index is transmitted to the receiver to enable reconstruction of the speech signal at the receiver.
