Low Delay Sparse and Mixed Excitation CELP Coders for Wideband Speech Coding
Code Excited Linear Prediction (CELP) algorithms are proposed for compression of speech in 8 kHz band at switched or variable bit rate and algorithmic delay not exceeding 2 msec.Two structures of Low-Delay CELP coders are analyzed: Low-delay sparse excitation and 15-eg1053cl mixed excitation CELP.Sparse excitation is based on MP-MLQ and multilayer
