Abstract :筆者らは,これまで,Single-Input Multiple-Output (SIMO) や Multiple-Input Multiple-Output (MIMO)および大規模MIMOにおける受信アンテナのハードウェアコスト削減法としてアンテナパターン多重 (Antenna Pattern Multiplexing; APM) 技術に着目して研究を行ってきた.本稿では,APMの原理について時変指向性利得として,周波数分割多重および符号分割多重に基づく周期波形を用いて説明を試み,単一のアンテナ系統から,複数の分離可能なアンテナ出力が得られることを示す.
We have been studied Antenna Pattern Multiplexing (APM) technique suitable for receivers of Single-Input Multiple-Output (SIMO), Multiple-Input Multiple-Output (MIMO), and massive MIMO systems. APM technique has potential to reduce the hardware cost of the receivers, for example, size of antenna, the number of required cables, cabling cost, calibration cost, maintenance cost, etc. In this paper, we try to explain the principle of APM with time-variable directional gain designed based on Frequency Division Multiplexing (FDM) and Code Division Multiplexing (CDM). Through the paper, we show how to obtain multiple distinguishable antenna outputs from a single Radio Frequency (RF) front-end.
