RX Quality
The output window
RX Quality
indicates the received signal quality determined by
the mobile for the signals of the CMU.
The received signal quality is expressed in terms of dimensionless quality levels
(actually “error levels”) depending linearly on the logarithm of the bit error rate. A
high quality level implies a high bit error rate and thus a
poor
received signal
quality:
