TL;DR: In this article, the authors proposed a novel constellation design for MIMO indoor VLC systems, in which the two symbols from two spaces collaborate so closely that the average optical power is minimized under the constraint that the minimum Euclidean distance is fixed.

TL;DR: In this article, a multi-LED phase-shifted OOK (MP-OOK) modulation was proposed for parallel transmission of visible-light communication with DC-biased optical orthogonal frequency division multiplexing (DCO-OFDM).

TL;DR: This paper designs two classes of energy-efficient time-dimensional constellations that are addition-unique and have remarkable performance gains over the currently available zero-forcing, minimum mean square error and time-division multiple access methods for the multiuser multi-input-single-output VLC broadcast systems.

TL;DR: This paper investigates the artificial noise (AN) aided physical layer security (PLS) for energy-based massive multi-input multi-output multi-access channels with finite-alphabet data inputs, where both the legitimate base station and the passive eavesdropper (Eve) are equipped with large antenna arrays and each user has multiple antennas.

TL;DR: Simulation results demonstrate that the training receivers can achieve full diversity and that the optimal power allocation scheme can improve the error performance significantly.
