Joint operation of forward error correction (FEC) techniques and automatic repeat request (ARQ) techniques are conducted above a physical layer of a communication network. Forward error correction is applied if the number of errors is equal to or less than an error threshold. Automatic repeat request techniques are applied if errors remain in the data decoding using the forward error correction or if an error correcting module reports a failure in the data. In an embodiment, the error threshold is two errors or less. In an embodiment, information is encoded in a data link layer using a forward error correction module providing a code rate of 0.98 or gre
part of the process. Several common examples of the case where some form of error handling is used are as follows : Data Storage and read on Memory, Harddisk, CD etc Serial Communication (RS 232) IP Communication Most of Wireless Communication (e.g, Mobile Communication like WCDMA, LTE etc) You would realize that most of digital data processing or communication would have not be realized if there is no mechism for error handling (error detection and correction) Followings are the topics that will be dealt in this page. What is Error ? What is Error Detection ? What is Error Correction ? Error Detection/Correction Techniques Parity Check Two Dimensional Parity Check Checksum Cyclic Redundancy Error (CRC) What is done if the reciever find the error ? What is Error ? First let's think of the definition of 'Error'. What is 'Error' ? It is simple. Error can be defined as 'any difference between the transmitted data and received data'. This may sound specific only to communication. In case of data storage, you can define Error as 'any difference between the data being sent for writing and the data really written on a media (e.g, Hard Disk, Memory or CD).' What is Error Detection? Once Error happened, we need to have some mechanism to figure out 'whether there exists any error' or'exactly where is the error occured'. This mechanism of finding the existence of error is called 'Error Detection'. If we know the exact contents of transmitted data, it would be very simple to find out the location of errors. Just simply by comparing the transmitted data and received data, we can easily find the location of errors. However in realty, we don't know what is the transmitted data (original data). So we have to figure out the location of errors only from the received data. This is why Error detection is not so simple. There are roughly two types of Error Detection as follows. A mechanism that tells on the existence of error, but does not tells on the location of errors. A mechanism that tells on both the existence of error and the location of errors. Of course, the second type is better in most case since it will give a chance for error recovery. But in most cases,
