- W2807617891 abstract "In this paper, optimization of diffuse spots' parameters in indoor optical wireless communications (OWC) system is carried out by using the particle swarm optimization (PSO) algorithm. By simultaneously optimizing the diffusion spots' locations and intensities, we show an improvement in the signal-to-noise ratio (SNR) and the delay spread at the receivers, while considering both the background noise and the multipath dispersion. A comparison is made between different optimization scenarios, to illustrate the effect of varying the parameters that are being optimized. We show that the optimization of both intensities and locations of diffuse spots resulted in improvement up to 42% and 23% in the average delay spread and the average SNR, respectively, compared with the centrally located position of diffuse spots' distribution, with respect to the receivers' locations, which has a uniform distribution of power." @default.
