Abstract
The Inverse Gaussian (IG) distribution has been recently proposed as a less complex alternative to the classical log-normal distribution to describe shadowing phenomena. This paper investigates the performance of digital communications systems over IG fading channels. Closed-form expressions for the outage probability and the average bit-error rate for various modulation schemes are derived. Moreover the performance of maximal-ratio and selection combining receivers is analyzed. The proposed analysis is accompanied with various numerical results that validate the theoretical analysis and provide useful insights into the implications of the model parameters on the overall system performance.
