A Nakagami-m fading channel simulator

The Nakagami-m distribution is well known for modeling the physical fading radio channel. The advantage of this model is that it can model signal fading conditions ranging from severe to moderate, to light fading or no fading, through its parameter m.; The performance analysis of diverse communication systems in Nakagami- m fading environments is widely investigated. Fewer results have been reported regarding the computer simulation of Nakagami fading.; This thesis gives a procedure for simulating both the amplitude and the phase process of a Nakagami-m fading channel, for arbitrary values of the fading parameter m. The direct inverse algorithm for generating Nakagami-m distributed random variates is introduced first. A method for approximating the inverse Nakagami- m CDR is derived for improving the efficiency of the direct inverse algorithm. This approximation method is also useful for fast calculation of the inverse Nakagami-m CDR The autocorrelation properties of the efficient simulator are examined in this thesis. Also addressed in this thesis are the efficiency analysis and the comparisons with other Nakagami- m fading channel simulation methods.; The proposed simulation procedure has certain advantages. The most important one is that it can model Nakagami-m fading for arbitrary m (½ ≤ 1, and 1 ≤ m < infinity) where other simulators have limitations. The advantages of the proposed simulation procedure are also addressed in this thesis.
