In future wireless communication systems, massive multiple-input multiple-output (MIMO) is attracting attention for improving transmission rate. However, there is an issue that a large scale of hardware is needed due to massive numbers of antennas, transmitters, receivers, A/D and D/A convertors in massive MIMO. In this study, we propose a method to realize a virtual massive array with only one receiver by changing the beam pattern and performing A/D conversion at high speed within one symbol. The basic performance and effectiveness of the proposed method is demonstrated via a computer simulation.
