I'ld like to ask about the most used Vocoder in GSM networks
Dose it require dynamic or adaptive channel coding?
How is it being implemented? of the shelf IC or ASIC or SWover RISC or DSP?
What's the computetional power MIPS/FLOPS needed for it?
In GSM Network, FER-13k is currently used vocoder. AMR is the new vocdoer with the adaptive channel coding. Check 3gpp website to find more information on FER, AMR.
