Abstract
A method of decoding speech data generated from a speech signal includes receiving the speech data having at least one main pulse in a subframe of the speech data, and generating a first predicted pulse, based on the at least one main pulse, on one side of the main pulse in the subframe of the speech data, where the first predicted pulse has a lower gain than the main pulse. The method also includes generating a second predicted pulse, as a mirror image of the first predicted pulse on a reverse time scale, on the other side of the main pulse in the subframe of the speech data, and reconstructing the speech signal using the at least one main pulse, the first predicted pulse and the second predicted pulse.
