Report
An analysis of the probable impact on communication systems of LSI (Large-Scale Integration), a new technology that enables placing the equivalent of hundreds of transistors on a single silicon pinhead. Included are a review of the communication sys...
Report
Part of a study undertaken to develop formal methods for investigating the design of optimal radar (and sonar) systems as a totality and in terms of functional elements, in a way that treats the physical model, the system purpose, and the criteria ...
Report
A discussion of means of sharing the radio frequency spectrum above 3400 MHz among terrestrial microwave relay, satellite relay, and satellite earth stations for fixed or mobile communication services, including direct broadcast from satellites. Eac...
Report
An evaluation of digital transmission techniques for miltiple access to a communication satellite. Specific features of digital techniques are examined: time-division multiplexing, error correction codes, analog-to-digital conversion methods, and syn...
Report
A tutorial, theoretical description of analog modulation methods, frequency-division multiplexing, and the signal processing techniques sometimes used with them in radio communication systems. Amplitude and angle modulation methods (AM DSB, SSB, PM, ...
Report
A mathematical description of a specific method for allocating time and frequency in communication satellite systems that use time-frequency multiplexing for multiple random access. This method of constructing addresses from a time-frequency matrix c...
Journal Article
Comments and replies between the author and colleagues on single-sided angle modulation (SSB-FM).
Report
A review of the field of power amplification at communication satellite frequencies.
Report
Presentation of a method for obtaining a navigation capability as a bonus to a communication satellite system. The Memorandum is primarily concerned with the technology of determining a user vehicle's position from a single satellite by obtaining mu...
Report
A restatement (with minor revisions) of material presented in "Design and use of an early communication satellite system," RM-3514, July 1963. The paper discusses technical factors of small ground terminal parameters, capacity for antenna patterns, c...
Report
(1) combines all sources of noise, including rain, as a function of frequency and elevation angle; and (2) presents estimates of time distributions of degradation of the down link due to rain for various system noise temperatures in the absence of rain.
Report
This publication is an attempt to assess the role of transportation and communication (the aggregate performance of which has not been measured before) in the Soviet Union's overall economic growth.
Report
A computational aid for designers of communication systems employing earth satellites as active relays.
Report
A comparison of costs of a worldwide communication system using microwave relay or communications satellites.
Report
A brief study of the network of submarine telephone cables. Since the first transatlantic cable was completed in 1956, the network has been expanding rapidly in world coverage and circuit capacity.
Report
A discussion of some of the international implications of communication satellite systems.
Report
An analysis of the value of available communication satellite techniques for establishing, in the near future, either low or medium capacity worldwide communication networks. The low-capacity net primarily would enable U.S. government agencies to com...
Report
A study of an important problem in designing communication satellite systems; namely, the choice of a method which permits several ground stations to have simultaneous access to the same satellite. One method is to assign a different transmitting fre...
Report
Text of a lecture given in January 1963 at IADC in five sections: (1) the most immediate contribution of space technology to hemisphere security is through application to the U.S. strategic deterrent force; ...
Report
A brief statistical analysis of the assumption that the growth of overseas telecommunications traffic has been, and will continue to be, intimately connected with the growth of overseas commodity trade. The record since 1950 does not support the view...
