A Network Shadow Fading Model for Autonomous Infrastructure Wireless Networks
In traditional cellular networks the Base Stations (BSs) are more or less regularly deployed. In the channel model for such networks, correlated channel gains are only considered between a BS and multiple terminals (or one terminal and multiple BSs). Although, the literature has introduced efficient techniques to produce correlated channel gains, to the authors' knowledge it has not reported on the correlation between pairs of links with no common end. This may be a reasonable model for large cell sizes (or equivalently the large inter-site-distances) in the traditional networks. In future networks, however, it is expected that a large number of BSs will be deployed in random positions. With the dense deployment of BSs, appropriate correlation channel models should be developed.
