چکیده
Both light emitting diode (LED) characteristics for illumination and communication simultaneously have made visible communication-orthogonal frequency division multiplexing (VLC-OFDM) a strong competitive to radio (RF). In this juncture, improve signal noise ratio (SNR) coverage contour, the wavelet-OFDM is suggested indoor VLC systems. paper, wavelet VLC-OFDM proposed imaging multiple-input multiple-output (MIMO) The exploited hybrid space-frequency domain pre-equalization technique instead of traditional fast Fourier transform (FFT)-OFDM technique. Meyer filter selected employed in A comparable achievement elaborated several numbers channels achieve enhanced performance terms bit rate contour. addition, useful comparison executed between our FFT-OFDM simulation results emphasize superiority point MIMO system by improving contour ~20% over OFDM at 10−3 error (BER) target. Hence, can be potentially VLC-MIMO

LAT Indoor MIMO-VLC
Visible Light Communications (VLC) is an innovative technology that uses the visible spectrum for high-speed data communications. In this paper we investigate the use of MIMO in the design of luminaires supporting VLC and, specifically, in enabling localization and high data rate services. Localization and transmission appear as two different problems in the communication system; however, the f...

In this paper we present and study the performance of an OFDM-MIMO system with unitary Space-Time Code for two channel states at the receiver: Perfect Channel State Information (perfect CSI), where we assume that the channel is perfectly known to the receiver. The second state is: Absence of Channel State Information (No CSI), where the channel information is not available at the receiver. In t...

In multiple-input multiple-output (MIMO) indoor visible light communication (VLC) systems, channel gains are highly correlated. As a result, the bit error rate (BER) of the system is degraded. To improve the BER performance of the system, we propose two precoders, namely, an optimal precoder and a diagonal precoder for MIMO schemes in VLC systems with Nt light emitting diodes (LED) and Nr photo...
