Abstract
A method provides mixed analog/digital beamforming by a transmitter in a mobile communication system. The method includes converting a modulation symbol into a parallel symbol stream performing digital beamforming on the parallel symbol stream performing an IFFT operation on the digital-beamformed parallel symbol stream to generate a time-domain symbol converting the IFFT-operated time-domain symbol into a serial time-domain symbol inserting a CP into the serial time-domain symbol performing a DAC operation on the CP-inserted symbol to generate an analog signal and performing analog beamforming by multiplying the analog signal by the analog beamforming precoder optimized for the first subcarrier transmitted through at least one RF channel.
