A duplex communication system is a point-to-point system composed of two or more connected parties or devices that can communicate with one another in both directions. Duplex systems are employed in many communications networks, either to allow for simultaneous communication in both directions between two connected parties or to provide a reverse path for the monitoring and remote adjustment ...
In telecommunications, communications-electronics (C-E) is the specialized field concerned with the use of electronic devices and systems for the acquisition or acceptance, processing, storage, display, analysis, protection, disposition, and transfer of information. [1] C-E includes the wide range of responsibilities and actions relating to:
Time-hopping (TH) is a communications signal technique which can be used to achieve anti-jamming (AJ) or low probability of intercept (LPI). It can also refer to pulse-position modulation, which in its simplest form employs 2 k discrete pulses (referring to the unique positions of the pulse within the transmission window) to transmit k bit(s) per pulse.
In telecommunications and electronics, baud (/ b ɔː d /; symbol: Bd) is a common unit of measurement of symbol rate, which is one of the components that determine the speed of communication over a data channel. It is the unit for symbol rate or modulation rate in symbols per second or pulses per second.
Ultra-wideband (UWB, ultra wideband, ultra-wide band and ultraband) is a radio technology that can use a very low energy level for short-range, high-bandwidth communications over a large portion of the radio spectrum. [1] UWB has traditional applications in non-cooperative radar imaging.
Communications are encrypted. This article incorporates text from this source, which is in the public domain. The Combat Capabilities Development Command (CCDC) C5ISR Center, [2] formerly the Communications-Electronics RD&E Center (CERDEC), is the United States Army information technologies and
ANT accommodates three types of messaging: broadcast, acknowledged, and burst. Broadcast is a one-way communication from one node to another (or many). The receiving node(s) transmit no acknowledgment, but the receiving node may still send messages back to the transmitting node.
One of the more ambitious projects involved tests installing radio communication equipment aboard Delaware, Lackawanna and Western Railroad trains, conducted in 1913. [17] In late 1915 the company announced the formation of the National Amateur Wireless Association (NAWA), an organization oriented towards amateur radio enthusiasts.
