Abstract

Disclosed are a terminal and a base station for a distributed array massive multiple-input and multiple-output (MIMO) communication antenna system and an operation method thereof, wherein the terminal includes a distribution analog unit receiving a plurality of analog array receive signals based on a terminal antenna transmit signal from a virtual terminal through a plurality of distributed antenna arrays and a digital unit restoring the terminal antenna transmit signal based on the analog array receive signals and a channel parameter, and the base station includes an antenna receiving an analog receive signal based on a transmit beamforming input signal from a plurality of distributed antenna arrays, a virtual terminal restoring the transmit beamforming input signal based on an amplitude of the analog receive signal, and a terminal receive signal mapper mapping the transmit beamforming input signal to a base station transmit signal.
