independent U.S. government agency which enforces campaign finance regulations (for candidates for the U.S. Senate, House of Representatives, President, and Vice President)
Forward Error Correction Technique for detecting and correcting errors (from imperfect transmission) by adding a small number of extra bits FEC allows optical transmission over longer distances by correcting errors that can happen as the signal-to-noise ratio decreases with distance See also Raman Amplification
The Federal Elections Commission, the federal agency that regulates the campaign finance laws and imposes penalties on candidates for federal office and members of Congress who violate those laws
Forward Error Correction Encoding system where extra or redundant data is added to a signal so that a receiver can not only detect but attempt to correct any errors with a high probability of success
Coding technique initially used in satellite transmissions then submarine transmissions, now widely used for optical transmission and in mobile networks The information transmitted is protected by introducing a redundancy that makes it possible for the receiver to correct part of the transmission errors Thanks to this technique, a link designed for 2 5 Gb/s transmissions without coding can thus be re-used at 10 Gb/s without requiring additional amplifying sites
Forward Error Correction A technique for improving the robustness of data transmission Excess bits are included in the outgoing data stream so that error-correction algorithms can be applied upon reception For the satellite standard the Viterbi code combined with the Reed Solomon code is used Commercial use of transponders makes 3/4 the code rate most used for Viterbi, which means that three out of four bits contain useable information
Full Name: Forward Error Correction Description: A methodology that uses error correction coding to transmission This is the opposite of ARQ (automatic repeat request) which uses retransmission of data
Forward Error Correction An error detection and correction technique based on the addition of a code to the signal at the transmitter A decoder in the receiver detects and corrects errors making use of the properties of this code The amount of coding information added to the original signal is quantified by the Code Rate
FEC (Forward Error Correction) is a fractional indicator of how much error correction code has been added to the original digital code being transmitted For example, if FEC is 7/8, then 7/8ths of the transmitted signal is the original code, and 1/8th is error code that has been added Different transponders may transmit with different amounts of error correction code embedded in the signal
A front end computer is a controller of a VXI/VME crate running VXWorks, connected via a network to the console computers The front end computer talks to various pieces of hardware
A technique used by a receiver for correcting errors incurred in transmission over a communications channel without requiring retransmission of any information by the transmitter; typically involves a convolution of the transmitted bits and the appending of extra bits by both the receiver and transmitter using a common algorithm
