As Error Correction
Contents |
(Discuss) Proposed since January 2015. In telecommunication, information theory, and coding theory, forward error correction (FEC) or channel coding[1] is a technique used for controlling errors in data transmission over unreliable correction of an error accounting or noisy communication channels. The central idea is the sender encodes the

message in a redundant way by using an error-correcting code (ECC). The American mathematician Richard Hamming pioneered this field in

the 1940s and invented the first error-correcting code in 1950: the Hamming (7,4) code.[2] The redundancy allows the receiver to detect a limited number of errors that may occur anywhere in

the message, and often to correct these errors without retransmission. FEC gives the receiver the ability to correct errors without needing a reverse channel to request retransmission of data, but at the cost of a fixed, higher forward channel bandwidth. FEC is therefore applied in situations where retransmissions are costly or impossible, such as one-way communication links and when transmitting to multiple receivers in error correction code multicast. FEC information is usually added to mass storage devices to enable recovery of corrupted data, and is widely used in modems. FEC processing in a receiver may be applied to a digital bit stream or in the demodulation of a digitally modulated carrier. For the latter, FEC is an integral part of the initial analog-to-digital conversion in the receiver. The Viterbi decoder implements a soft-decision algorithm to demodulate digital data from an analog signal corrupted by noise. Many FEC coders can also generate a bit-error rate (BER) signal which can be used as feedback to fine-tune the analog receiving electronics. The noisy-channel coding theorem establishes bounds on the theoretical maximum information transfer rate of a channel with some given noise level. Some advanced FEC systems come very close to the theoretical maximum. The maximum fractions of errors or of missing bits that can be corrected is determined by the design of the FEC code, so different forward error correcting codes are suitable for different conditions.

Marguerite is worried about how she is to deal with error correction with her beginning Spanish classes. She wants to correct her students and thereby improve the quality of their language, but is afraid that if she corrects the students too much, they will become discouraged and stop taking risks in the language. back to... Erinn's case study Marguerite's case study What does the process of error correction consist of? Error correction sequences consists of four steps: A student error The teacher’s feedback which may take the form of explicit correction, recast, clarification request, metalinguistic feedback, elicitation or error correction The student’s response, which may or may not still need repair Reinforcement of a correct response by the teacher (on occasion) Students respond more successfully when the correct form is not supplied for them and there is negotiation of form ie: with clarification requests, metalinguistic feedback, elicitation or error repetition What is the difference between intake and uptake? Intake occurs during the process of Giving It and Getting It, where students are taking in new information and processing it. Uptake occurs during the Using It stage and describes the process of students retrieving information that is already part of their consciousness. It describes the learners’ responses to the teacher's feedback following either an erroneous utterance or a query about a linguistic item. Some researchers argue that uptake may contribute to second language acquisition by facilitating noticing and pushing lea
