An Approximation of the Outage Probability in Rayleigh-lognormal Fading Scenarios
نویسندگان
چکیده
In this report we propose an approximation of the outage probability of the Signal to Interference plus Noise Ratio for a CDMA system in a Rayleigh-lognormal fading environment. Specifically, the SINR is approximated as an overall lognormal random variable. The approximation moves from the one proposed in [1] for the product of Rayleigh-lognormal random variables, and from the method presented in [2] for the approximation of the sum of weighted lognormal random variables. Numerical results show that our approach performs quite well for any situation of practical interest.

A unified expression for computing the probability of outage in cellular mobile radio systems is derived. The method handles non-integer Nakagami fading indexes, unequal Rice factors, dissimilar shadowing spreads, unequal transmit powers as well as all the common fading distributions (Rayleigh, Rice, Nakagami-m, Nakagami-q, lognormal-Rice, Suzuki and lognormal-Nakagami-m). The exact outage prob...

In this paper, the performance analysis of an energy detector is exploited over composite multipath/shadowing fading channels, which is modeled by Rayleigh-lognormal (RL) distribution.
