Abstract :
The topic of the paper is the evaluation by the receiver of the power of noise and co-channel interferences altering transmissions over Rayleigh fading channels. In our study we display results for TDMA mobile radio systems such as GSM or EDGE, but the approach is valuable for CDMA as well. We propose two methods to carry out the evaluation of the signal to noise ratio (SNR) or the carrier to interference ratio (CIR) at each received burst. The accuracy of these methods are derived in a closed form in the case of additive noise. In the case of interferences, we display results of simulations for both methods when the number of interferers is between 1 and 6
