1	Bandwidth Efficient Signaling Using Multiscale Wavelet Functions and its Performance in a Rician Fast Fading Channel Employing Differential Detection Moon, Todd K., Lo, Chet 10 1900 (has links) International Telemetering Conference Proceedings / October 25-28, 1999 / Riviera Hotel and Convention Center, Las Vegas, Nevada / In this paper, orthogonal wavelets are employed to produce multiscale signaling. It is shown that signaling using these functions is bandwidth efficient compared other signaling schemes, including SFSK and GMSK. For signaling in Rician fast fading channel, it is also shown that scaling functions is superior in term of achieving low level of probability of error. Even for multiscale signaling, the level probability of error achieved by using wavelet is lower than conventional flat-top signaling. The benefits are largest for channels with small B(D)T , in which the degradation due to fading is most severe. Differential phase shift keying Fast Rician fading channels Wavelet Bandwidth efficient

3	DPSK modulation format for optical communication using FBG demodulator / DPSK modulering för optisk kommunikation med demodulering av FBG Jacobsson, Fredrik January 2004 (has links) <p>The task of the project was to evaluate a differential phase shift keying demodulation technique by replacing a Mach-Zehnder interferometer receiver with an optical filter (Fiber Bragg Grating). Computer simulations were made with single optical transmission, multi channel systems and transmission with combined angle/intensity modulated optical signals. The simulations showed good results at both 10 and 40 Gbit/s. Laboratory experiments were made at 10 Gbit/s to verify the simulation results. It was found that the demodulation technique worked, but not with satisfactory experimental results. The work was performed at Eindhoven University of Technology, Holland, within the framework of the STOLAS project at the department of Electro-optical communication.</p> Electronics DPSK Differential phase shift keying PSK FBG Fiber Bragg Grating MZI Mach- Zehnder optical communication optical signal WDM Wavelength division multiplexing TU/e Eindhoven Holland electro-optical communication optisk kommunikation elektrooptisk kommunikation Elektronik Electronics Elektronik
