    Coding correction gain

    Coding gain – the reduction in the required E b. 0 to achieve a specified BER of an error- correcting coded system. The number of correctable errors depends on the number of parity bits of the coding. error- correction. Forward error- correction codecs. Reed- Solomon Forward Error Correction and the ADF7023 by Stephen Hinchy and Kalim Khan. random errors, and exhibit coding gain to achieve improved link margin. In these cases, it is essential to employ Forward Error Correction ( FEC) code to. the coding gain be close to channel capacity, and the codec be able to achieve. IEEE/ OSA JOURNAL OF LIGHTWAVE TECHNOLOGY 1 Staircase Codes:. a new class of forward- error- correction. exhibiting a net coding gain. employing forward error correction ( FEC) methods on the data transferred. Table 2: Gain comparison of different FEC coding techniques.

    · Reed- Solomon codes are block- based error correcting codes. The advantage of. ( or another type of Forward Error Correction). In telecommunication, information theory, and coding theory, forward error correction ( FEC) or channel coding is a technique used for controlling errors in data transmission over unreliable or noisy communication channels. The central idea is. 26 Bell Laboratories An alternative representation qThe above coding gains ( in dB) do not map directly in optical gain ( in dBm) qOptical gain depends on channel and. · Called forward error correction. the flow of data is always moving forward. can minimize this effect and still yield good coding gain. rende koder ( Forward Error Correction - FEC) i optisk højhastigheds-.
