چکیده
ETRI adopt AMR codec for developing the 3GPP based IMT-2000 system. This paper presents the software and hardware implementation of multichannel AMR codec. The real-time implementation of AMR codec algorithm is achieved using TMS320C62xx DSP chip. We describe the efficient software scheme for implementing AMR codec and detailed hardware design. The multi-channel AMR codec is evaluated and confirmed in 3GPP test sequences, stand-alone test system and ETRI IMT2000 prototype system.

متن کاملAn adaptive multi-rate speech codec based on MP-CELP coding algorithm for ETSI AMR standard
This paper proposes a speech codec based on the MultiPulse based CELP (MP-CELP) coding and a convolutional coding algorithms for the ETSI Adaptive Multi-Rate (AMR) standard. The codec operates at several speech coding rates, maintaining a fixed gross rate including speech and channel coding for the Full-Rate (FR) and Half-Rate (HR) channel modes. MP-CELP has great features of easily changing th...
