Taschenbuch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The new integrated system of visible free space optic and broadband powerline communication which uses already installed powerline cables and white LEDs as a communication channel is presented. The currently exist problems in integrated system degrades the whole system performance significantly. Therefore, in this work, an optimum OFDM modulating signal power, proper DC biasing point and LED dynamic range are presented for the integrated system. Besides using OFDM modulation a practical LED model is also presented and the performance of integrated system in terms of OFDM signal power versus BER in the presence of BPLC impulsive noise and multipath issue and also AWGN optical channel is studied. As another major contribution of this project, the radiometric parameters of white LEDs using simulation and experiment are reported. The experiments show a tolerable match with the simulated results. The new integrated system which is applied for indoor applications has the data rate more than 28Mbits/second with the bit error rates lower than . So the new integrated system can be considered as a good alternative for other indoor wireless system counterparts. 68 pp. Englisch.

Paperback. Zustand: new. Paperback. A novel system of dark soliton array (DSA) for secured communication generated by using the multiplexed dark soliton pulses is proposed. The multi soliton pulses with relevant parameters are input into the micro ring resonators system with the radii of 10 mm and 5 mm, where the dynamic dark solitons can be controlled and generated. The DSA are obtained by using a series micro ring resonators with parameters where in the wavelength range of 1.56, 1.58 and1.60. For security applications, the DSA can be tuned and amplified. Thus, the use of DSA for high capacity which can be realized by using proposed secured system. In transmission, the long distance link of the multi variable network can be performed by this DSA.
