| Abstract(in English) | In this paper, we propose a transmission beamforming design for the multiple input single output (MISO) system consisting of a multiple-antenna transmitter and multiple receivers with defferent sizes of cache memories. Efficient beamforming designs are proposed to transmit required packets with different sizes upon applying coded caching to them. We reveal that our proposed schemes achieve higher transmission rate than conventional scheme via computer simulation. |
