This dissertation is organized as follows. Beginning with physical background discussions of many-body problems, Chapter 1 introduces the central Kohn-Sham equations of Density Functional Theory for e...
Effect of Atmospheric Turbulence on Acquisition Time of Ground to Deep Space Optical
Atmospheric Turbulence Acquisition Time Binary Phase Shift Keying (BPSK)
2010/2/2
The performance of ground to deep space optical
communication systems is degraded by distortion of the beam as it
propagates through the turbulent atmosphere. Turbulence causes
fluctuations in the ...
State-Space Synthesis of Current-Mode First-Order Log-Domain Filters
Log-domain filters current-mode circuits state-space synthesis
2009/7/28
This paper proposes current-mode first-order log-domain filters, which are systematically derived using the state-space synthesis procedure. First-order low-pass, high-pass, and all-pass responses are...
