Abstract EN
The streaming of wireless applications and growth in bandwidth demand led to huge interest in Ultra Wide Band (UWB) technology.
In this paper a Wavelength Division Multiplexing (WDM)-UWB system based Optical Wireless Communication (OWC) is designed and simulated with two modulation formats OOk and QAM at three bit rates values(1Gbps, 2.5Gbps and 5Gbps).
In the designed system, two methods to generate UWB pulses are proposed and demonstrated, optical method based cross-gain modulation (XGM) in a Semiconductor Optical Amplifier (SOA) and the electrical method depends on the differentiation of the Gaussian pulse.
The full width half maximum (FWHM) of the generated pulses (monocycle and doublet) are 32 ps, 19ps for optical method and2.2 ns, 1.9ns for electrical method.
All the generated pulses are compatible with the Federal Communications Commission (FCC) rules .In order to understand the linear and nonlinear effects, and the maximum achievable reach at each modulation scheme, the performance of the system is tested under four cases of weather conditions: clear, rainy, fog and snow weather with single channel and 8-WDM channels at 100GHz, 75GHz and 50GHz channel spacing.
