Wireless Free Space Optics (FSO) is one of the most promising candidates for future broadband communications, offering transmission rates far beyond possible by RF technology. However, free space wireless optical channel presents far more challenging conditions for signals than typical RF channels, making system availability and throughput a critical issue.(More)
Free Space Optical Communications through cloud-obscured channels suffer from severe degradations due to multiscattering, which induces delay spread in the received signal. The delay spread of FSO channel can vary considerably according to channel conditions, varying from nanoseconds to microseconds for clear and cloudy channel, respectively. In this paper,(More)
—Coexistence of Wi-Fi and LTE in unlicensed spectrum (LTE-U) is recently drawing significant concern in industry. In this paper, we investigate the Wi-Fi performance in the presence of duty cycle based LTE-U transmission on the same channel. More specifically, one LTE-U cell and one Wi-Fi basic service set (BSS) coexist by allowing LTE-U devices transmit(More)
