Beamforming (BF) is essential to achieve a throughput gain by using Massive multiple-input multiple-output (MIMO). However, the overhead for obtaining channel state information and its feedback to the transmitter is a severe problem in the closed-loop BF control based on the MIMO channel state information. Therefore, in this paper, we study an open-loop type BF control, which does not rely on the channel state information, based on firefly algorithm (FA). FA is a kind of swarm intelligence and by mimicking the behavior of fireflies which moves toward neighbor fireflies based on distance and brightness of the neighbor fireflies, the solution to the multimodal optimization is obtained efficiently. By setting the BF vector as a position of the firefly and the obtainable throughput by using that BF vector as a brightness of the firefly, we apply the FA to the BF control. We show several variants of updating method of BF vector considering its norm constraint and updating order among multiple fireflies and evaluate the throughput performance of them by using computer simulations. |
