  In the framework of the "Smart ElectroMagnetic Environment" (SEME), an
innovative strategy leveraging Equivalence Source concepts is introduced for
enhancing the performance of large-scale outdoor wireless communication
systems. The proposed Opportunistic Sources Synthesis (OSS) approach is aimed
at unconventionally synthesizing the primary source (i.e., the base transceiver
station (BTS) antenna array), so that the complex scattering phenomena induced
in the surrounding scatterers are profitably exploited to enhance the received
power within user-defined regions of interest (RoIs). To yield a
computationally feasible synthesis process, an innovative
"Embedded-plus-Environment Patterns" (EPEPs) method is introduced. A set of
representative numerical examples, concerned with realistic large-scale outdoor
scenarios, is presented to assess the effectiveness and the efficiency of the
proposed optimization-driven approach for a realistic SEME implementation.
