Modeling and simulation of fast fading channels in indoor peer-to-peer scenarios

Traditional cellular solutions are coming under increasing pressure from wireless peer-to-peer (P2P) systems. The growing interest in wireless indoor communication systems has resulted in many investigations on the characteristics of indoor radio propagation channels. In [?], various properties of indoor peer-to-peer channels have been analyzed for static nodes only. In [?], peer-to-peer channels were investigated in a typical US office environment, consisting in a large indoor area containing individual cubicle-style offices. The same environment was also used in [?] to investigate the multi-user separation in duallink MIMO indoor scenarios. In this paper, we investigate narrowband indoor distributed channels based on an experimental campaign in an office environment. We evaluate the fast fading statistics using the second-order scattering fading (SOSF) distribution. It turns out from the measurements that the fading statistics change over time. An approach to model these effects is proposed.
