    Forward error correction is the process by which the recipient attempts to believe redundant elements using a message. Retransmission correction is an excellent technique in which the receiver identifies the occurrence of an error and therefore requests the sender to resend the message.


    Forward Error Correction (FEC) is an error correction format in which a message is represented in redundant cases, allowing the receiver to unnecessarily recover lost bits. and

    What is forwarding error correction?

    In telecommunications and information coding theory, Forward Error Correction (FEC), or distribution channel coding, is a technique used to control errors in data transmission over unreliable or noisy communication channels.

    FEC works by adding “control bits” to my outgoing data stream. Adding more test bits reduces the available bandwidth by increasing the overall size of the outgoing data neighborhood, but also allows the receiver to recover from more errors without adding more transmit data to the receiver. Dynamic

    This makes FEC ideal when bandwidth is sufficient but retransmission is expensive or impossible.

    The “control bits”, or redundant bits that the sender adds to the downloaded data, are encoded in the data in a special way that allows for efficient error correction on the receiving device. Simplified

    An example is triple redundancy code, also known as repetition code. Where (3,1) each data bit is simply transmitted three times. The results of the two triples are averaged together, corrected and the result is just a choice.

    Other more advanced encoding schemes are usedThose used so far include Reed-Solomon HTML encoding, a custom encoding scheme that can be widely used in DVB.Of

  • Reed-Solomon encoding is notable for the fact that CDs, DVDs, and hard drives use bit errors corrupted by physical damage to the disc’s working media.

    Forward error correction is especially well suited for satellite transmission, both for consumer applications and for file mining applications where the throughput is medium, the delay is high.>


    Error Correction And Reverse Error Correction

    Forward error correction protocols require more bandwidth than reverse error correction protocols, but unfortunately can recover from complications faster and with much fewer retransmissions.


    Forward error correction is also particularly computationally intensive for the user device, since the redundant information must be interpreted according to the givenalgorithm during the transfer of the entire.

    What is the difference between backward and forward error correction?

    Reverse Error Correction: As only certain errors are detected, the receiver asks the entire sender to retransmit the entire block of numbers. Forward Error Correction: In one case, the receiver automatically uses any error correction code that corrects a particular error.

    In general, forward error correction is more suitable for large-scale transmissions over distance and with relatively high levels of noise, rather than situations where small amounts of normally related information can be retransmitted and smoothly. In these cases, reverse error correction is likely to be suitable.

    Forward Error Correction (FEC) is a technique for minimizing errors in file transfers over communication channels. transmission With real-time multimedia, retransmission of corrupted as well as lost packets does not make sense, since it only generates an unacceptable playback delay: it must be postponed until the lost or damaged box is retransmitted. Therefore, there must be a method that often corrects the error and reproduces the packet without delay, giving the receiver the ability to correct errors without requiring the reverse channel to request a retransmission of data. There are several steps for this. Simple FEC .

    1.Using Hamming distance:
    For error correction, the minimum distance is X The mmming required for error handling, Alt=” is:

    forward error correction and retransmission

    For example, if 20 errors need to be corrected, the minimum von de Hamming distance is 2*20+1= bit 41. This means that many redundant bits must be sent along with the document. This method is used very rarely because we have to send large amounts of data over their networks, and in most cases, such extreme redundancy is unacceptable.

    2. Using XOR.
    The Is Or method is very useful because data items can usually be recreated using this method. .The .XOR property .used .as .below .– .–

    forward error correction and retransmission

    If the XOR property is applied to N data items, we can exactly recreate all items from the P1 data set to P N for exclusive OR all elements, replacing the person with the result of the previous operation (R). In this method, the package is dividedDivide into N then parts, create exclusive large parts or all, and then send N 1+ parts. Usually, when a song is lost or damaged, it can be automatically recreated by the recipient side.

    Practically, if n=4, this means that 25% more data needs to be sent, and the data can be changed if only one of the four defined blocks is lost.

    3. Alternation of fragments. method
    This breaks each data packet into fragments. Personal information is then created piece by piece (horizontally), but the pieces are bundled vertically along. This is mainly because each package ends up containing part of several pre-packages. When a packet is sacrificed, we miss out on only one part of each, which is what the packet is normally allowed to do in multimedia communications. Some small small parts may be missing as you head towards the receiver. Usually you can allow one piece to be missing from the La deck once, since you cannot allow all the pieces from one deck to be missing.
