ATIS is the leading technical planning and standards development organization committed to the rapid development of global, market-driven standards for the information, entertainment and communications industry.
A diversity combiner in which (a) the signals from each channel are added together, (b) the gain of each channel is made proportional to the rms signal level and inversely proportional to the mean square noise level in that channel, and (c) the same proportionality constant is used for all channels. Synonyms ratio-squared combiner, post-detection combiner, predetection combining, selective combiner.
Industry:Telecommunications
A diversity combiner in which the combining consists of simple addition of two or more signals.
Industry:Telecommunications
A diversity combiner in which the signals on each channel are added. Note: The channel gains can be made to remain always and everywhere equal so that the resultant signal remains approximately constant.
Industry:Telecommunications
A document that establishes engineering and technical requirements that are necessary to be employed in the design of systems, units, or forces and to use the services so exchanged to enable them to operate effectively together.
Industry:Telecommunications
A DOD standard protocol designed for use in interconnected systems of packet-switched computer communication networks. Note: The internet protocol provides for transmitting blocks of data called datagrams from sources to destinations, where sources and destinations are hosts identified by fixed-length addresses. The internet protocol also provides for fragmentation and reassembly of long datagrams, if necessary, for transmission through small-packet networks.
Industry:Telecommunications
A domain name including all higher level domain names up to the top-level domain name; for example: Paris. Nisc. Sri. Com is a fully qualified domain name for the host at 192. 33. 33. 109; nisc. Sri. Com is the fully qualified domain name for the NISC domain. Note: The fully qualified domain name must be unique within the Internet.
Industry:Telecommunications
A domain name of an Internet resource indicating its type or its capabilities. Note: One Internet resource may have a set of different domain names, one of which is the preferred one. Example: www. Isi. Edu denotes a host containing a Web server.
Industry:Telecommunications
A domestic telecommunications network usually accessed by telephones, key telephone systems, private branch exchange trunks, and data arrangements. Note: Completion of the circuit between the call originator and call receiver in a PSTN requires network signaling in the form of dial pulses or multifrequency tones.
Industry:Telecommunications
A double-length key used to compute another key cryptographically. Note: The derivation key is normally used (in receiving a transaction) to derive or decrypt the transaction keys used by a great number of originating terminals.
Industry:Telecommunications
A downlink circuit that provides a terminal with information regarding uplink acquisition and synchronization status.
