Speech coding is one of the fundamental concepts for the accommodation of number of users in a communication channel. Many algorithms are used for speech coding. A variant of Codebook-Excited Linear Prediction (CELP) speech coding is widely used in wireless telephone communication (most of CDMA networks uses this type of vocoder), and has been accepted as the international standard for transmission of speech over telephone networks. This project explains what CELP speech coding is, why it is necessary for wireless communication, and describes unique design of a CELP speech coder. The CELP...
