Communication links, Productivity, knowledge transfers, growth and income distribution
In this study, we show that banking development, communication links, productivity and income distribution exert a statistically and economically significant positive impact on local economic growth. This effect becomes more pronounced when the financial sector is more liberalized and deregulated. …

Comparison of Direct and Heterodyne Detection Optical Intersatellite Communication Links
… and heterodyne detection optical intersatellite communication links are evaluated and compared. It is shown that the performance of optical links is very sensitive to the pointing and tracking errors at the transmitter and receiver. In the presence of random pointing and tracking errors, optimal …

Adaptive gain spatial receiver for wide dynamic range communication links
Wireless optical communication facilitates high-speed transmission across long distances. However, time-varying and spatially-dependent attenuation through freespace channels due to scattering impedes operation for many wide dynamic range links. In the atmosphere, communication is often limited to …

The dynamic behavior of rain attenuation on satellite communication links
The proposed use of communication satellites operating above 10 GHz has stimulated research into the effects of atmospheric rain and ice on the reception of these signals. This thesis examines the statistics of fade rate, fade duration, and interface intervals on 19 and 28 GHz communication links, …

Capactiy of single-hop communication links in wireless ad hoc networks
This thesis defines the capacity of single-hop communication links in wireless ad hoc networks as the transferable data rate over that link determined by the Shannon limit and by the fixed modulation scheme and bit error rate. The resulting capacity formulas are derived under the assumption of …
