Level-Crossing Rate and Average Duration of Fades of the Envelope of Mobile-to-Mobile Fading Channels in Cooperative Networks Under Line-of-Sight Conditions
This paper studies the fading behavior of Mobile-To-Mobile (M2M) fading channels in relay-based cooperative networks under Line-Of-Sight (LOS) conditions. Here, the authors assume that LOS components exist in both the direct link between the Source Mobile Station (SMS) and the Destination Mobile Station (DMS) as well as in the link via the Mobile Relay (MR). In such a propagation environment, the fading channel is referred to as the Multiple-LOS Second-order Scattering (MLSS) channel. The fading behavior of MLSS channels is studied by analyzing the Level-Crossing Rate (LCR) and the Average Duration of Fades (ADF) of the received envelope.
