【Abstract】 The 4. 8kbps ACELP algorithm is a kind of speech coding scheme applied to Digital Trunking System. This algorithm adopts algebraic codebook as excitation, and has the features of high synthesis tone quality and low coding delay. This paper briefly analyses the basic principle of ACELP algorithm and presents an implementation scheme of this algorithm using DSP in Digital Trunking System.更多还原
