The purpose of the paper is to demonstrate a general and rigorous CAD procedure that can potentially provide a systematic answer to the needs of modern circuit-level microwave system simulation/design by combining nonlinear, electromagnetic (EM), and propagation analysis tools. As examples of application a systematic approach to a full CAD-based treatment of Multi-Input Multi-Output (MIMO) and Ultra Wide Band (UWB) links is presented. The EM theory allows to evaluate a set of Norton equivalent generators to derive a circuit description of the receiver excitation: in the MIMO case one generator for each ray coming from each transmitting antenna; in the UWB case one generator for each harmonic frequency used to describe the spectrum of the Impulse-Radio (IR)-UWB signal. For the first time, highly-complex RF links can be otpimized by means of the rigorous circuit-level CAD tool here presented: the selection of both the optimum distance between the receiving antennas and the optimum transmitted pulse shape is numerically performed in the MIMO and UWB case, respectively.

Abstract
The purpose of the paper is to demonstrate a general and rigorous CAD procedure that can potentially provide a systematic answer to the needs of modern circuit-level microwave system simulation/design by combining nonlinear, electromagnetic (EM), and propagation analysis tools. As examples of application a systematic approach to a full CAD-based treatment of Multi-Input Multi-Output (MIMO) and Ultra Wide Band (UWB) links is presented. The EM theory allows to evaluate a set of Norton equivalent generators to derive a circuit description of the receiver excitation: in the MIMO case one generator for each ray coming from each transmitting antenna; in the UWB case one generator for each harmonic frequency used to describe the spectrum of the Impulse-Radio (IR)-UWB signal. For the first time, highly-complex RF links can be otpimized by means of the rigorous circuit-level CAD tool here presented: the selection of both the optimum distance between the receiving antennas and the optimum transmitted pulse shape is numerically performed in the MIMO and UWB case, respectively.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
