Distortion Analysis of RF Links by Means of Circuit-Level Nonlinear/EM Front-end Simulation and Realistic Channel Description

End-to-end analysis of RF/microwave links is addressed for the first time by combining rigorous circuit-level nonlinear analysis of the transmitting and receiving front ends, electromagnetic (EM) characterisation of the antennas, and realistic description of the radio channel. The latter is a multipath model based on a 3D ray tracing (RT) approach. The connection between transmitter and receiver is established by a full EM computation of the radiated far field under modulated input drive
