The Hilbert Generator, a Filter-Free Upconverter for 6G Communications

Abstract

This paper presents a new type of architecture for the conversion of wide frequency bands to high frequencies beyond 100GHz in order to overcome technological obstacles for 6G. It is proposed to consider the Hilbert transform as a mathematical tool for the design of a system natively rejecting the image frequencies in order to save on blocks like filters and mixers. It is shown that an appropriate conversion makes it possible to reject images of the order of several tens of dB, in simulation with CW, modulated (64-QAM) and multi-carrier signals. An experiment is carried out, at low frequencies, to demonstrate the concept.
