NB for CSD/HSCSD and WB for UMTS/HSDPA.
The UMTS/HSDPA services already provides an
excellent turbo code correction.
For what i know i can tell you more about corrupted packets.
The BER ranges from 10^-5 to 10^-2 for CSD/HSCDS
in transparent mode, and from 10^-9 to 10^-6 for
UMTS/HSDPA.
It depends on signal quality and if you're
walking/standing or if you're in real mobility
(for example talking while driving a car), etc...
So it depends. For example, if it is raining, the water
causes lots of refletions and rises the BER.
Rural environments has less BER than urban ones.
In order to undestand your 4 points i suppose i need
to study CELP becouse i'm not understanding right now.
Have you
other suggestions given these informations?
Thanks.
