The prediction of BER performance in the GSM radio system

This paper presents a method of predicting the bit-error rate (BER) performance of the global system for mobile communications (GSM) system as a function of the wideband channel parameters obtainable from measured or assumed power delay profiles. Although delay spread is found to be the most useful parameter for the prediction of BER performance, it has been shown that in some conditions delay interval (15 dB) can provide a more accurate prediction mechanism. Thus, based on the delay spread and the delay interval (15 dB), empirical prediction formulas are derived.
