Mobile radio channel simulators are essential for repeatable system tests in the development, design, or test laboratory. Field tests in a mobile environment are considerably more expensive and may require permission from regulatory authorities. Because of the random, uncontrollable nature of the mobile propagation path, it is difficult to generate repeatable field test results. The Nakagami model can be used to test the performance of radios in a mobile environment in the lab, without the need to perform measurements whilst actually mobile. The mobile fading simulation can also if required be replicated, and the effects can be varied according to the ‘velocity’ of the mobile receiver. This allows the comparison of the performance of different receivers under standardized conditions that would not normally be possible in actual mobile testing situations. In this paper, two techniques that are capable of generating correlated Nakagami channels with arbitrary fading parameters are proposed. Basically our approach is to generate Nakagami RVs from the square root of directly generated correlated Gamma RVs (not from sum of squares of Gaussian RVs).
