Quantization noise of signal correlators.Klingler, Rolf Jerg January 1972 (has links)
In radio-astronomy, spectra of noisy signals are often computed using digital auto-correlation techniques. To simplify the design of the many high-speed multipliers and averagers, coarse quantization is employed, using only a few digital levels.
This thesis is a theoretical study of the penalty paid for such coarse quantization in the form of increased output noise. A degradation factor is defined and is calculated for a variety of logic schemes which have been used or proposed.
For each scheme, results are given as a function of sampling rate and it is demonstrated that there is often significant improvement in sampling at rates faster than the Nyquist rate.
A computer simulation technique was developed for verifying the computed results, and for extending the results to complicated schemes where analysis is very difficult. / Applied Science, Faculty of / Electrical and Computer Engineering, Department of / Graduate

Frequency and polarization diversity simulations for Urban UAV communication and data linksPala, Fatih. 09 1900 (has links)
Approved for public release, distribution is unlimited / The purpose of this research was to examine the effects of frequency, and polarization on radio wave propagation in urbanized areas for unmanned aerial vehicle (UAV) data links, and command and control. The transmission from a UAV operating over a small city was simulated using the Urbana Wireless Toolset. Parameters that were varied include frequency, antenna polarization, UAV altitude, and building materials. Multiple reflections and diffractions were included in the simulation. In each case signal contours were generated at discrete frequencies over a 50 MHz bandwidth. It was observed that the signal levels varied up to over the bands at a fixed observation point due to frequency-dependent reflection and diffraction. / 1st Lieutenant, Turkish Air Force
