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: 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.
