For multihop/Ad-hoc networks, the conventional one-dimensional (1-D) channel model cannot capture the spatial correlation of the shadowing processes. This paper investigates the joint spatial/temporal correlation property the shadowing process for peer-to-peer radio links in urban environments. Statistical analysis reveals that the shadowing process is mainly a result of the movement at the mobile station (MS) side. Furthermore, the joint correlation property of the MS-MS channel shows that MS movement at each end of the peer-to-peer link have independent and equal effect on the correlation coefficient. A filter based joint shadowing process simulation model is proposed for urban peer-to-peer radio channels. Simulations illustrate the potential of the proposed channel model
