Level-crossing rate and average duration of fades of deterministicsimulation models for Rice fading channels

摘要

The concept of Rice's sum of sinusoids is often applied to thendesign of deterministic simulation models for Rice fading channels. Thisnpaper investigates in detail the level-crossing rate (LCR), averagenduration of fades (ADF), and cumulative distribution function (CDF) ofnsuch classes of simulation models. Exact and simple approximativenformulas are deduced for these statistical quantities. Several numericalnresults for the derived expressions are presented by using differentnprocedures for the design of the parameters of the deterministicnsimulation model. Moreover, comparisons with the correspondingnsimulation results-obtained by evaluating the deterministic simulationnmodels output data-are also given
