Neuware - Space agencies are under pressure to utilize better bandwidth-efficient communication methods due to the actual allocated frequency bands becoming more congested. Also budget reductions is another problem that the space agencies must deal with. This budget constraint results in simpler spacecraft carrying less communication capabilities and also the reduction in staff to capture data in the earth stations. It is then imperative that the most bandwidth efficient communication methods be utilized. This thesis presents a study of 8-ary Phase Shift Keying (8PSK) modulation with respect to bandwidth, power efficiency, spurious emissions and interference susceptibility over a non-linear satellite channel.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Taschenbuch. Condizione: Neu. Neuware - This research investigates the effect of pulse shaping QPSK on bandwidth efficiency over a non-linear channel. This investigation will include software simulations and the hardware implementation. Three kinds of filters: the 5th order Butterworth filter, the 3rd order Bessel filter and the Square Root Raised Cosine filter with a roll off factor (alpha) of 0.25,0.5 and 1, have been investigated as pulse shaping filters. Two different high power amplifiers, one a Traveling Wave Tube Amplifier (TWTA) and the other a Solid State Power Amplifier (SSPA) have been investigated in the hardware implementation. A significant improvement in the bandwidth utilization (rho) for the filtered data compared to unfiltered data through the non-linear channel is shown in the results. This method promises strong performance gains in a bandlimited channel when compared to unfiltered systems. This work was conducted at NMSU in the Center for Space Telemetering, and Telecommunications Systems in the Klipsch School of Electrical and Computer Engineering Department and is supported by a grant from the National Aeronautics and Space Administration (NASA) NAG5-1491.…

Taschenbuch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - The contributions to this volume explore eleven key developments in the external history of the German language, that is, the combination of social, political and cultural circumstances which influenced the language and its speakers. Some of these 'landmarks' are individuals or groups of people who have exerted influence over the language: Charlemagne, Luther, the early modern grammarians and lexicographers. Others are studies of particular periods, places or groups which have not found their place in more narrative accounts: standardisation in the nineteenth century, the role of Low German, the state of German at the Stunde Null in 1945. An overarching theme is the role of deliberate intervention in the development of German, whether it took the form of education, prescriptivism, purism or political manipulation. The essays, a number of which were originally delivered as lectures in the University of Cambridge and all of which are by specialists in the field, combine to provide a history of the German language in its social context.…
