Abstract

This review paper presents for analysis between code excited linear prediction and algebraic code excited linear prediction speech coding techniques which is useful in wireless communication for compression of speech signal to improve the data rate. from this paper we understood CELP encoder, decoder & ACELP encoder, and decoder & differentiate both the coding technology. How it used in WCDMA wireless communication system, the major factor in speech coding is bit rate which is reduced in ACELP coder up to 4.6kbps.Compare to CELP coder. In many applications for transmission of voice signal it conversion is needed for that speech coder is used.
