1 The purpose of this paper is to study how the different propagation environments as well as antenna configurations impact on the performances of space-time block coded (STBC) MIMO systems. Based on the geometrical differences such as one-ring model and elliptical model with different distributions of scatters, the comparisons on system performances are presented here. The impacts of the mean ...

We study the geometric properties of the energy landscape of coarse-grained, off-lattice models of polymers by endowing the configuration space with a suitable metric, depending on the potential energy function, such that the dynamical trajectories are the geodesics of the metric. Using numerical simulations, we show that the fluctuations of the curvature clearly mark the folding transition, an...

Bistatic configuration is an attractive concept for spaceborne and airborne SAR missions when distributed radars are necessary as for example in the case of interferometric applications. The first reason is the important cost reduction achieved over the multiple radar elements, by having only one transmitter (expensive part) and multiple receivers. The most promising applications are single-pas...
