Abstract
Algebraic Code-Excited Linear Prediction (ACELP) is a popular linear prediction speech coding algorithm that provides good performance with reasonable implementation complexity, and requires low transmission bit rate. The excitation sequence is formed as the sum of two quantized excitations: an adaptive (pitch) codebook excitation and an algebraic (fixed) codebook excitation. Algebraic codevectors are sparse.
