Compressed sensing structured illumination microscopy
(IEEE-Institute of Electrical and Electronics Engineers Inc, 2020)We propose a new framework for super-resolution structured illumination microscopy (SR-SIM) based on compressed sensing (CS). Our framework addresses several key problems in SIM, including long readout time and photobleaching. ... -
Dynamic sidelobe multiplexing in beamspace MIMO systems
(IEEE-Institute of Electrical and Electronics Engineers Inc, 2020)Recent studies on multiplexing concept over beamspace multiple-input-multiple-output (MIMO) can reduce the need for using phase shifters while keeping the directivity performance at similar levels. Thus, beamspace MIMO ... -
Experimental validation of a novel RLL code for visible light communication
(IEEE-Institute of Electrical and Electronics Engineers Inc, 2020)Flicker arising in visible light communication (VLC) system is typically mitigated by run-length-limited (RLL) codes. The IEEE 802.15.7 standard proposes RLL codes according to the modulation type and data rate. In this ... -
Impact of mutual coupling on power-domain non-orthogonal multiple access (NOMA)
(IEEE-Institute of Electrical and Electronics Engineers Inc, 2020)This paper investigates the impact of mutual coupling (MC) on the achievable sum-rate of power-domain non-orthogonal multiple access (NOMA) system in both uplink (UL) and downlink (DL) transmissions. We assume a single-antenna ... -
