On The Generation of Autocorrelated α-η-κ-μ Fading Sequences

The α-η-κ-μ probabilistic model offers a general, unified description for all the essential ingredients of short-term fading. Thus far, however, it has no associated simulator as general as the model itself, becoming less attractive to design teams of real-world wireless systems. The only simulator available is limited to integer and half-integer values of the (real-valued) μ-parameter—a condition never strictly met in practice. In this work, we overcome this drawback by proposing a simulation method that allows for real values of the μ-parameter, exactly matches the first-order statistics of the α-η-κ-μ model, and closely approximates its second-order statistics. This last requirement is a long-standing issue in fading simulation.
