Abstract

A transceiver of a user equipment includes a receiving stage, a frontend channel estimator, a frontend channel equalizer, a backend channel estimator, and a backend channel equalizer. The receiving stage is configured to receive an inbound signal from a SUDAC, which enables a relay communication including a frontend communication using extremely-high frequencies and a backend communication using ultra-high frequencies. The inbound signal includes a data portion, a backend control portion and a frontend control portion, the frontend control portion including a frontend evaluation signal and a configuration signal. The frontend and the backend channel estimators are configured to perform channel estimations based on the frontend evaluation signal and the backend control portion, respectively, wherein the frontend and backend channel equalizers are configured to equalize distortions, caused by using the extremely-high and ultra-high frequencies, respectively, based on the channel estimation of the frontend and backend channel estimators, respectively.
