“…A similar approach has been proposed by Kavehrad and coworkers, who performed theoretical and experimental work on subcarrier transmission of electronic CDMA signals using optical fiber as the transmission medium and Surface Acoustic Waves (SAW) matched filtering reception [116,117]. This work maps into an optical fiber domain the same techniques that some years ago were employed in wireless LANs, and it is indicative of the close relationship of such schemes with the radio CDMA.…”

“…Since the infrared wireless LAN systems are constituted by simple and cheap units, the infrared wireless LAN systems can be realized easier than the fiber optic (FO) systems that need optical fibers [3] [4]. Compared with radio wireless systems, infrared radiation (IR) offers many advantages, such as a higher bit rate, an enormous unregulated bandwidth, a high security, and so on.…”

In this paper, we propose optical wireless multipleinput multiple-output (OMIMO) with backward spatial filter (BSF) in diffuse channels. In the proposed system BSF is constructed based on the channel state information (CSI) in the transmitter so that the received signal is free from multipath interference, which results in less receiver complexity and good performance. We show that the proposed system can achieve better bit error rate (BER) performance than the conventional single-input single output (SISO) system in diffuse chanels.

We analyze the performance of the atmospheric optical subcarrier multiplexing (AO-SCM) systems and the atmospheric optical code division multiplexing (AO-CDM) systems. We derive the average received carrier-to-interference-plus-noise ratio (CINR) of the AO-SCM systems and the AO-CDM systems on a turbulence channel with the scintillation and the nonlinearity of an LD. We show that the received CINR of the AO-CDM systems is larger than that of the AO-SCM systems when the number of channels is small for the same optical modulation index (OMI), and vice versa when the number of channels is large for the same OMI. For instance, when the logarithm variance of scintillation σ 2 X is 0.3, a constant of the nonlinearity of an LD a3 is 0.17, and the number of channels K is 4, the maximum CINR of the AO-CDM systems is about 4 dB better than that of the AO-SCM systems. Also, when K is 16, the maximum CINR of the AO-SCM systems is about 3 dB better than that of the AO-CDM systems. The difference of CINR results in the difference of the maximum achievable number of channels for the systems. When the required BER is 10 −9 , AO-SCM and AO-CDM systems can accomodate 16 and 8 BPSK channels, respectively.
