“…A 4×4 MIMO VLC scheme with a commercial charge-coupled device (CCD) as an image sensor receiver was demonstrated in [4]. An experimental 4×4 MIMO VLC achieved a data rate of 10 Gbit/s using a vertical cavity surface emitter laser (VCSEL) [5]. MIMO techniques coupled with OFDM and equalization [6], spatial modulation [7], and spatial multiplexing [8] have been proposed in the literature.…”

A 2 Gbit/s visible-light communication (VLC) scheme using time-frequency color-clustered (TFCC) multiple-input multiple-output (MIMO) based on blue, cyan, yellow, and red (BCYR) light-emitting diodes (LEDs) is presented. In the proposed scheme, BCYR LEDs are employed to form four different color clusters. Data transmission using the four color clusters is performed in MIMO, so that the scheme achieves a very high speed of data transmission. Moreover, the scheme employs the TFCC strategy to yield high performance in terms of bit error rate (BER). TFCC operates in such a way that the original data and the two delayed versions of the data are multiplied by orthogonal frequencies and then transmitted using a specific color of the BCYR LED. In the receiver, color filters are employed to detect the data transmitted from the desired cluster. Selection combining (SC) is also performed to yield a diversity effect within each color cluster, to further improve the performance. Performance evaluation demonstrates that the proposed TFCC MIMO VLC offers a data rate of 2 Gbit/s and a bit error rate of 4×10 , at an Eb/No value of merely 3 dB.

“…Also, it does not facilitate diversity benefits. Recently, 4 × 9 MIMO using vertical cavity surface emitter laser (VCSEL) has been reported [5]. It encompasses 16 QAM and orthogonal frequency-division multiplexing (OFDM) at a distance of 15 m free space transmission link.…”

A novel color clustered optical RGB multiple-input multiple-output (MIMO) system is presented. As visible light can be divided into three primary regions of red, green and blue, data can be modulated and transmitted separately using these three color clusters. Each color cluster comprised of 30 RGB LEDs is modulated using on-off-keying (OOK), and selection combining is performed at the receiver, producing a diversity effect within that color cluster. The simulations demonstrate that the proposed RGB MIMO VLC system provides high performance via a relatively simple design of MIMO. Moreover, the proposed system ensures sufficient illumination from LEDs and offers extended distance if more LEDs are applied.

“…Visible light communication (VLC) using LED [1][2][3][4][5][6][7][8] is considered as a promising wireless communication system with low electromagnetic interference (EMI) to the existing radio-frequency (RF) communication. Over the last decade, mobile phones with a built-in complementary metal-oxide-semiconductor (CMOS) camera is becoming popular, providing the ability to capture photos and videos.…”
