• Part of the book series (LNCS, volume 2524) Abstract ETRI adopt AMR codec for developing the 3GPP based IMT-2000 system. This paper presents the software and hardware implementation of multi-channel AMR codec. Pa Rn License Renewal Registration Code. 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 IMT-2000 prototype system.
