Multilevel sequences and line codes

Botha, Louis 13 May 2014 (has links)
M.Ing. (Electrical Engineering) / As the demand for high-speed data communications over conventional channels such as coaxial cables and twisted pairs grows, it becomes neccesary to optimize every aspect of the communication system at reasonable cost to meet this demand effectively. The choice of a line code is one of the most important aspects in the design of a communications system, as the line code determines the complexity, and thus also the cost, of several circuits in the system. It has become known in recent years that a multilevel line code is preferable to a binary code in cases where high-speed communications are desired. Apart from ternary codes, not many multilevel codes are available. Some of the existing line codes also suffer from serious drawbacks regarding a lack of complying to input restrictions, small values of efficiency, and great code complexity. In this study, Markov models and values of channel capacity are presented for several classes of restricted multilevel sequences which are thought to be of practical importance in view of the channel input restrictions that these codes satisfy. Different coding methods are used to construct low-complexity encoders and decoders for generating and decoding these sequences with high values of efficiency, good error behaviour and favourable power spectral densities

Flexible Intercom System Design for Telemetry Sites and Other Test Environments

Bougan, Timothy B. 10 1900 (has links)
International Telemetering Conference Proceedings / October 28-31, 1996 / Town and Country Hotel and Convention Center, San Diego, California / Testing avionics and military equipment often requires extensive facilities and numerous operators working in concert. In many cases these facilities are mobile and can be set up at remote locations. In almost all situations the equipment is loud and makes communication between the operators difficult if not impossible. Furthermore, many sites must transmit, receive, relay, and record telemetry signals. To facilitate communication, most telemetry and test sites incorporate some form of intercom system. While intercom systems themselves are a not a new concept and are available in many forms, finding one that meets the requirements of the test community (at a reasonable cost) can be a significant challenge. Specifically, the test director must often communicate with several manned stations, aircraft, remote sites, and/or simultaneously record all or some of the audio traffic. Furthermore, it is often necessary to conference all or some of the channels (so that all those involved can fully follow the progress of the test). The needs can be so specialized that they often demand a very expensive "custom" solution. This paper describes the philosophy and design of a multi-channel intercom system specifically intended to support the needs of the telemetry and test community. It discusses in detail how to use state-of-the-art field programmable gate arrays, relatively inexpensive computers and digital signal processors, and some other new technologies to design a fully digital, completely non-blocking intercom system. The system described is radically different from conventional designs but is much more cost effective (thanks to recent developments in programmable logic, microprocessor performance, and serial/digital technologies). This paper presents, as an example, the conception and design of an actual system purchased by the US government.
