Detection processes for digital satellite modems

The aim of this study is to devise detectors for digital satellite modems, that have tolerances to additive white Gaussian noise which are as close as possible to that for optimal detection, at a fraction of the equipment complexity required for optimal detection. Computer simulation tests and theoretical analyses are used to compare the proposed detectors. [Continues.

Philosophy: digital humanities

The textbook supplements the lecture material with topical issues of philosophy in the field of social semiotics and digital linguistics. The technological trends in the evolution of convergent structures of digital ecosystems are described. The evolution of social semiotics in conjunction with digital linguistics is analyzed

Earth Resources: A continuing bibliography with indexes, issue 1

This bibliography lists 616 reports, articles, and other documents introduced into the NASA scientific and technical information system between January 1974 and March 1974. Emphasis is placed on the use of remote sensing and geophysical instrumentation in spacecraft and aircraft to survey and inventory, natural resources and urban areas. Subject matter is grouped according to agriculture and forestry, environmental changes and cultural resources, geodesy and cartography, geology and mineral resources, oceanography and marine resources, hydrology and water management, data processing and distribution systems, instrumentation and sensors, and economic analysis
