TL;DR: The studies show that the SNR fluctuation under such a LED lamp arrangement is reduced from 14.5 dB to 0.9 dB, which guarantees that users can obtain almost identical communication quality, regardless of their locations.

TL;DR: The purpose of this paper is to study and compare the bit-error-rate (BER) performance of several widely used modulation formats under different atmospheric turbulence scenarios with and without SDRT, and derives a series-form formula for evaluating the BER performance of the DPSK format in the Gamma-Gamma distributed channel with SDRt.

TL;DR: BER and signal-to-noise-ratio performances of the proposed precoding multiuser (MU) MIMO system in indoor visible light communications (VLC) with the consideration of the mobility of user terminals are investigated.

TL;DR: The results show that with different duty cycles the required data rates are not higher than the original value and less LED lamp power is required to guarantee the communication quality, which makes the dimming control system that satisfies both communication and illumination requirements easy to be implemented and power-saving.

TL;DR: A scheme to improve the SNR distribution as well as the spectral efficiency of M-QAM OFDM signal for indoor visible light communication by tilting the receiver plane by employing Newton method.
