In this blog post, we will describe some of the possible reasons that might cause the error to be found and then I will provide some possible solutions that you can try to solve this problem.

To prevent errors, we use error detection codes, which are additional data appended to a digital message, to tell us if an error occurred while transmitting the message. The main approach to error detection is the ad hoc use of redundant bits, where additional bits are added to facilitate troubleshooting.
In dataset theory and coding theory, as well as in computer science and telecommunications concepts, error diagnosis and error correction or loss are methods that allow digital data to be reliably transmitted over unreliable communication channels. Many communication channels are subject to channel noise, so errors can occur during transmission from source to destination. Error detection techniques help detect these slips, and error correction can in many cases recover the original data.

Errors is the detection of errors caused by noise or certain imperfections during the transmission from each of our transmitters to the receiver.
Error correction is the precise detection of errors and the restoration of the original data without errors.
In classical antiquity, scribes of the Hebrew Bible were paid for their work based on the number of engravings (verses). Since prose books are relativelyBible references were rarely depicted on paper in engravings, scribes had to count the letters in order to correctly estimate the number. This also helped to ensure the accuracy of the tradition. text with to ensure subsequent copies are made. Digital Massora to ensure accurate reproduction of the sacred text. This included summing up the number of words in a large number of lines, paragraphs, books, and book villages, marking the center line of the book, word usage results, and comments. considered unacceptable. The effectiveness of their error correction is confirmed only by the accuracy of copying over the centuries of discoveries made, which were undoubtedly demonstrated by the Dead Sea Scrolls of 1947-1956, approximately 150 av. in AD 75
The modern growth error of corrective codes is due to Richard Hamming in 1947. The description of the Hamming code appeared along with Claude Shannon’s “Mathematical Theory” related to I-communication[7 ] . was quickly generalized to Marcel JE Golay.
What are 3 error detection techniques?
Error detection methods There are three main methods for detectingFrame dilemmas: parity check, checksum, and cyclic redundancy check (CRC).
All error detection and correction methods add some redundancy (that is, a bit of extra data) to information that recipients can use to compare the consistency of a delivered message and then repair data that is found to be corrupted. Error detection and correction schemes can be methodical or unsystematic. In the systematic method, the sender transmits the original bandwidth and adds a fixed number of parity bits (or parity data) specially obtained from the data components in part by a deterministic algorithm. If only true error detection is required, the system can simply apply the same criteria to the received data bits and therefore compare its output to the asserted parity bits; If the values don’t match, something went wrong at some point during the broadcast. In a system using a non-systematic specific code, the original message is actually converted into an encrypted one witha message containing the same information and offering at least as many bits as the original message.
Good error control requires that the performance of a circuit be determined based on the characteristics of a particular communication channel. Common channel models include memoryless models, in which errors occur randomly and with some probability, and hence dynamic models, in which errors mostly occur in bursts. Thus, error detection and correction codes can generally be distinguished in terms of random error detection/correction and burst error detection/correction. Some codes may also contain many random errors and transition errors at the end.
When the channel characteristics cannot be detected or are very different, an efficient error detection scheme can be combined with the system’s ability to retransmit erroneous data. This is known as Automatic Say Request (ARQ) and is mostly used on the internet. The switching approach to error control is automatic cross-request (HARQ), whichth is treated as an ARQ pattern during error correction coding.

Which is the best method of error detection?
The best-known error detection method is called parity, which involves adding an extra available bit to one byte of data and assigning a new value of 1 or 0, depending on whether a very even or odd number is tied to “1”. pieces.
Automatic retry request is (arq) a data transfer error control technique that uses added error detection codes, acknowledgment and/or negative advice messages, and timeouts to ensure genuine data transfer. An acknowledgment is a message sent by a receiver in the marketplace to indicate that it has successfully received a data frame.
If the sender does not receive an acknowledgment before the timeout (i.e., within a reasonable time after sending the frame), it will typically retransmit that frame until it is received without problems or until an error occurs. will disappear, and for a predetermined amount of rebroadcast. types
There are three protocols associated with ARQ: stop and wait ARQ, N-return ARQ, and selective repeat ARQ.
ARQ is suitable when the transmitting TV channel has other or unknown possibilities, as is the case with the Internet. However, ARQ requires access to the reverse channel, introduces possible increased delay due to retransmissions, and requires the maintenance of buffers and timers for retransmissions, which, in case of network congestion, imposes a load on the entire node and network bandwidth. . >
For example, ARQ is used as ARQ-E for shortwave information and fact references, or in combination with multiplexing as ARQ-M.
