  • Digital speech coder having improved long term lag parameter determination
    Patent number: 5097508
    Abstract: A method and apparatus is provided for determining the lag of a long term filter in a code excited linear prediction speech coder. An open loop lag is first determined using an autocorrelation function. The open loop lag is then utilized to generate a limited range over which a closed loop search is performed. The range for appropriate values includes lags that are harmonically related to the open loop lag as well as adjacent lags.
