Dears, Anybody knows about the tones effects in cell vocoders(QCELP and VSELP)? I have to detect a pilot tone (1400Hz i.e) in mobile phones (CDMA and TDMA) and I guess I might have some problems. Are there some research materials about that to QCELP and VSELP? Thanks/Regards. Elias Kopcak. CPqD Foundation. |
