Compared with the "fast modes" (JT9E-H), FT8 is significantly more sensitive, has much narrower bandwidth, uses the vertical waterfall, and offers multi-decoding over the full displayed passband. The mode also supports two-pass decoding and use of " a priori (already known) information as it accumulates during a QSO".
Digital Signal 1 (DS1, sometimes DS-1) is a T-carrier signaling scheme devised by Bell Labs. [1] DS1 is the primary digital telephone standard used in the United States , Canada and Japan and is able to transmit up to 24 multiplexed voice and data calls over telephone lines.
GNU Radio is a free software development toolkit that provides signal processing blocks to implement software-defined radios and signal processing systems. It can be used with external radio frequency (RF) hardware to create software-defined radios, or without hardware in a simulation-like environment.
The STS-1 payload is designed to carry a full PDH DS3 frame. When the DS3 enters a SONET network, path overhead is added, and that SONET network element (NE) is said to be a path generator and terminator. The SONET NE is line terminating if it processes the line overhead. Note that wherever the line or path is terminated, the section is ...
DS1 or DS-1 may refer to: BOSS DS-1, a guitar distortion pedal; Digital Signal 1, a T-carrier signaling scheme devised by Bell Labs; Deep Space 1, a mission to 9969 Braille & 19P/Borrelly; DS-1 (drug), a selective GABA A α4β3δ agonist drug; South African Class DS1, a diesel locomotive class; Datsun DS-1, a car by Nissan, see Datsun DS Series
Digital Signal Designation is the classification of digital bit rates in the digital multiplex hierarchy used in transport of signals from one location to another in telecommunications.
An update of RSS is CPS, a Windows-based version of the package used for some of Motorola's newer radio models. Radios are connected to PCs via the serial port, [2] and proprietary programming cables. The use of genuine Motorola OEM programming cables is strongly suggested, as aftermarket brands are not as reliable and could lead to radio damage.
In HDSL, full duplex by means of echo cancellation is used, enabling simultaneous transmission in both directions on each of the two wire pairs, effectively reducing the symbol rate by a factor two. Through the use of 2B1Q encoding, two bits are combined to one symbol, further reducing the symbol rate by a factor of two.
