Dear all:
"The AMR Codec mode adaptation is based on a normalized one-dimensional measure of the channel quality, called the Quality Indicator. For reference purposes, the Quality Indicator is defined as an equivalent carrier to interferer ratio, C/Inorm. The MS and BSSs shall continously update the Quality Indicator estimates.
The Quality Indicator may be derived from an estimate of the current carrier to interferer ratio, C/Iest , or an estimate of the current raw bit error rate (BERest)."
Can anyone tell me the difference between C/Inorm and C/I that is shown in TEMS cellphone?
