Error ratios employed in conjunction with GSM speech channels which are illustrated below:
i) Frame Erasure Rate, FER, is stated as the amount of swept speech frames (or 260 bits each) divided through the amount of transmitted speech frames. Speech frame is swept if even one of its most imperative 50 bits is observed not to be accurate. The three parity bits following the 50 class IA bits are employed for error recognition.
ii) Bit Error Rate, BER, is the ratio of incorrectly received bits to every received bit. It is imperative to notice which BER is evaluated ere channel decoding, that is, after equalizer. BER is employed for defining the RXQUAL value.
