Virtual Signal Calibration for 5G Circuit excitation and Optimal Beam Steering
Introduction
The arrival of the 5G has considerably changed the design process of wireless communication systems. In this new generation, there is a need to improve the area throughput, but allocating more bandwidth (physically impractical) and deploying more base stations (high deployment cost, inter-cell interferences) is not feasible.
Therefore, new modulation and multiplexing techniques are necessary to improve the spectral efficiency per cell using the base stations (BSs) and bandwidth already in place. Beamforming in phase arrays and massive MIMO is used to improve the architecture's performance.
Under these conditions, antenna designers face new challenges: theoretical beam steering is modified when connecting the antenna to the rest of the systems in the radio chain. Thus, a collaboration between designers in charge of each system becomes more relevant to achieving the expected overall performance, and a tool that all of them can use becomes necessary.
This white paper presents a new approach based on the simulation of accurate behavioral models to analyze undesired effects when connecting each system to improve beam steering.
