Abstract(in English) | In the massive multiple-input multiple-output (MIMO) downlink, transmitter beamforming (BF) to achieve a beamforming (power) gain and/or a reduction in inter-user interference in a multiuser MIMO case based on the channel state information (CSI)-feedback from the user terminals is essential. Massive MIMO requires a large number of transmitter power amplifiers dedicated to each of the transmitter antennas, and the allowable transmit power per power amplifier (thus per transmitter antenna) is severely limited. Therefore, it is necessary to perform transmission BF considering the limitation on the transmit power per antenna. In this paper, we apply our previously reported BF control using the FA to frequency selective transmission BF control under the presence of multiple frequency blocks. By considering the set of BF matrices generated for each frequency block as a position of the firefly and the obtainable metric for the system throughput maximization as a brightness of the firefly, we apply the FA to the BF control. We evaluate the performance of BF control using FA under the presence of multiple frequency blocks when the system throughput is defined as the geometric mean user throughput by using computer simulations and compare them with the case using conventional zero forming (ZF)-based BF. |
