Utilizing a complex-number basis for single-pixel imaging (SPI) a spatial wavefront in high quality is still an open issue. To solve this issue, here, we proposed a method called OAM-basis spatial …
In this paper, we investigate physical-layer security for the indoor single-input single-output (SISO) DC-biased optical orthogonal frequency division multiplexing (DCO-OFDM) visible light communic…
