Abstract [en]

In many modern wireless communications systems (e.g., in OFDM based digital audio broadcasting/digital video broadcasting (DAB/DVB), CDMA) the received signal can be a superposition of multiple useful and interfering lognormal components, and correlation may exist between the components. We propose a simple method for estimating the correlation coefficient between the total useful and total interfering signals as the function of the correlation between the individual components. We show that, by taking into account this correlation factor in the derivation of the distribution of the signal-to-interference ratio, considerable accuracy improvement can be achieved in the outage probability estimation.
