Adaptive 10 Gbit/s Mobile Optical Wireless Systems Employing Beam Delay, Angle and Power Adaptation with Imaging Receivers

In this paper, the authors propose a novel mobile Optical Wireless (OW) system that employs for the first time beam delay adaptation, and makes use of angle and power adaptation in a line strip multibeam spot diffusing configuration in conjunction with an imaging receiver (BDAPA-LSMS). Their ultimate goal is to improve the bandwidth, reduce the effect of Inter-Symbol-Interference (ISI), and increase the Signal to Noise Ratio (SNR) when the transmitter operates at a higher data rate under the impact of multipath dispersion, background noise and mobility. An increase in channel bandwidth from 36 MHz, typical in a Conventional Diffuse System (CDS), to about 9.8 GHz can be achieved when their methods of beam delay, angle and power adaptation coupled with an imaging receiver are employed.
