Evaluation of Optimum Multi-Channel Implementation of CS-ACELP Codec on TMS320C6205

Today, voice over IP applications and mobile communications require low-cost, low-delay and high-efficient speech coders. Conjugate-Structure Algebraic CELP (CS-ACELP) is a type of voice coding algorithm that compresses speech signal based on model parameters of human voice. Real time DSP (Digital S...

Summary:Today, voice over IP applications and mobile communications require low-cost, low-delay and high-efficient speech coders. Conjugate-Structure Algebraic CELP (CS-ACELP) is a type of voice coding algorithm that compresses speech signal based on model parameters of human voice. Real time DSP (Digital Signal Processor) implementation and optimization of this codec, described in this paper, is done on TMS320C6205. Also multi-channel implementation of the algorithm is evaluated.
