| Abstract(in English) | In this paper, we investigate the transmitter beamforming (BF) control based on the firefly algorithm (FA) in massive multiple-input multiple-output (MIMO) downlink with per-antenna power constraint, aiming at the maximization of the variously defined system throughput. In massive multiple-input multiple-output (MIMO) downlink, the transmitter BF to achieve the beamforming (power) gain and/or reduction in inter-user interference in multiuser MIMO case based on the channel state information (CSI) is essential. Massive MIMO requires large number of transmitter power amplifiers dedicated to each of transmitter antennas and allowable transmission power per power amplifiers (thus per transmitter antenna) is to be severely limited. Therefore, it is necessary to perform transmission BF in consideration of the limitation on the transmission power per antenna, which is in general difficult problem to solve. In this paper, we apply our previously reported BF control using the FA under various definitions of the system throughput considering the tradeoff between the frequency efficiency and user fairness. By setting the BF matrix 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 when the system throughput is as the arithmetic mean, geometric mean, harmonic mean, and minimum user throughput by using computer simulations and compare them with the case using conventional zero forming (ZF)-based BF. |
