Performance of Wireless Systems in the Presence of Multipath Fading, Gamma Shadowing and Cochannel Interference

Dr. Dragana Krstic
Faculty of Electronic Engineering
University of Nis

Abstract: Wireless communication system operating over Gamma shadowed Rician multipath fading environment in the presence of cochannel interference exposed to multipath fading and/or Gamma long term fading is investigated. In interference limited channel, signal to interference ratio (SIR) can be presented as the ratio of product of random variable with Rician, Nakagami-m, k-µ or some other distribution and squared root of Gamma random variable and Rician (Nakagami-m, k-µ..) random variable . The closed form expressions for probability density function, moment generating function and moments of output signal to interference ratio are efficiently calculated. The influences of Rician factor of desired signal, Rician factor of cochannel interference, Nakagami-m short term fading severity parameter, Gamma long term fading severity parameter and other distribution parameters on probability density function and moments of the first and the second order are analyzed and discussed.
