Abstract: The present disclosure relates to a computer system for maximizing wireless energy harvesting using an intelligent reflection surface and a method thereof. A multi-path channel including a direct channel through which power is directed from an ET apparatus toward an EU apparatus and a reflection channel through which the power is directed from the ET apparatus toward the EU apparatus after being reflected by an IRS apparatus may be implemented. The computer system may be designed to maximize a gain of the multi-path channel in order to maximize the harvested power.

Abstract: A method for simultaneous design of a hybrid transceiver in an OFDM-based wideband multi-antenna system is provided. The method comprises: designing transmission/reception analog beamforming commonly used for each subcarrier by using product information of subcarrier channel information; and designing baseband beamforming for an effective channel of each subcarrier.

Abstract: Disclosed are a method and an apparatus for controlling a quadrature amplitude modulation-filter bank multi-carrier (QAM-FBMC) system. A method of controlling interference is performed by a reception apparatus of the QAM-FBMC system, wherein the reception apparatus is paired with a transmission apparatus. The method includes receiving a pre-coded data symbol; and removing residual interference caused due to a non-orthogonal filter from the pre-coded data symbol by using a decision feedback equalizer.

Abstract: A communication system and an operating method thereof are for single carrier wideband hybrid beamforming based on limited feedback. A transmitter having a plurality of Tx antennas may be configured to receive limited channel information from at least one receiver each having at least one Rx antenna, schedule a RF beam for at least one stream in the receiver using the limited channel information, and perform baseband beamforming based on the RF beam.
