Answer / ravi
Error ratios used in conjunction with GSM speech channels:
· Frame Erasure Rate, FER, is defined as the amount of swept speech frames (260 bits each)
divided by the amount of transmitted speech frames. The speech frame is swept if even one of
its most important 50 bits is observed not to be correct. The three parity bits following the 50
class Ia bits are used for error detection.
· Bit Error Rate, BER, is the ratio of erroneously received bits to all received bits. It is
important to notice that BER is evaluated before channel decoding, i.e. after equaliser. BER is
used for defining the RXQUAL value

Answer / s.narsimha swamy
FER= No.of Error Frames/Total No.of Fremes
The FER lies between 0 to 100%
BER= No.of Error Bits/Total No.of Bits
for good signal BER lies between 0 to 26%
