Abstract :
This paper presents a new unified analytical method for efficient computation of first and second order statistics of the signal-to-interference-plus-noise-ratio (SINR) in wireless communication systems. New exact expressions are derived for the moments of SINR and its autocovariance function that are valid for arbitrary interfering signals. These are used to examine the accuracy of the commonly used approximations for the average SINR and to investigate effects of fast fading and interfering signals´ temporal behavior on the autocorrelation properties of SINR.
