CELP and LPC  
This short article provides information on CELP (stands for "code excited linear prediction") and LPC ("linear predictive coding"). They are compression algorithms used for low bit rate (2400 and 4800 bps) speech coding.

ACELP (Algebraic Code Excited Linear Prediction)  
ACELP (Algebraic Code Excited Linear Prediction) is an efficient technology for speech compression at bit rates around 8kbps. ACELP achieves its efficiency through the use of algebraic codebook that requires no storage with fast searching procedure. ACELPâ technology is widely used. Some examples are GSM EFR, G.729 and 723.1.

Evaluation of some DTFM Algorithms  
Performance evaluation and real-time implementation of subspace, adaptive, and DFT algorithms for multi-tone detection. Evaluation of MUSIC, LMS, and the Goertzel algorithms for dual-tone multiple-frequency estimation. The issue rates their computational requirements, estimation errors, and their compliance with the CCITT Q.23 and Q.24 standards through MATLAB simulations and real-time implementations on the ADSP-2101 and Motorola 56001 processors.
