Optical Wireless Communication has been an active area of research due to its diverse application fields. In this work, the main focus is on performance analysis of high speed low power inter satellite optical wireless communication (LP-IsOWC) on the basis of bit error rate (BER), Q-factor, signal power etc. Conventional intersatellite communication uses radio frequency (RF) system. RF systems have many drawbacks, which can be overcome by optical intersatellite links. Licenses and regulations are the limitation of RF satellite communication system. Large, unregulated spectrum is there in free...

In a micro-cellular RoF network a fiber-fed distributed antenna system is established. Each remote antenna receives radio frequency signals and transmits them over optical fiber link up to a central station for signal processing. A RoF system can further be enhanced by incorporating the dense wavelength division multiplexing (DWDM) technique for bandwidth utilization and ultra high speed communication. The present work aims to present a model for such a RoF system that operates at a high speed while having huge capacity. After an extensive literature review over the topic it was concluded...

Gemcitabine is a nucleoside analogue, used in various carcinomas such as non small cell lung cancer, pancreatic cancer, ovarian cancer and breast cancer. The major setbacks to the conventional therapy with gemcitabine include its short half-life and highly hydrophilic nature. The objectives of this investigation were to synthesize lipophilic derivative of gemcitabine, evaluate the physiochemical properties, entrapment efficiency, in vitro release, cytotoxicity, and cellular uptake of nanoparticulate formulations containing gemcitabine and stearoyl gemcitabine. We successfully prepared a...

Optimization of the optical wireless channel using WDM and DWDM technique is demonstrated. Designing and analysing the optical network is firstly executed. Cascaded amplifiers are used at power level of 12 dB and with net spectral efficiency that is 6.45 b/s/Hz. The cascaded amplifiers employed enhanced the Q-factor and BER of the system and the gain achieved of the system was satisfactory. The signals are transmitted at a distance of 10,000 km with channel spacing of 100 GHz in conventional optical band (1530- 1565 nm). DWDM is used at the channel spacing of 100GHz and the bandwidth of the...
