Error Correction Code refers to a coding technique used in computers to identify and fix errors in data transmission. Unlike error-detecting codes, error correction codes not only detect errors but also attempt to repair them, ensuring reliable data transfer. ...
A typical error detecting code is the CRC-CCITT code (widely used in data communication) which has a generator polynomial x16 +x12 +x5 +1. The CRC-CCITT code detects all single bursts errors of sixteen bits or less and double bursts errors of four bits or less. It is bit serial. ...
the CRC code is the remainder when the picture data of one scanning line is divided by a generator (X4+X+1). In an expansion mode, the compander 15 is composed of the line buffer 31; the expander 36 (MH reverse conversion); an EOL detector 37 for detecting an EOL added to the conv...
The central concept in detecting and/or correcting errors is redundancy in that the number of bits transmitted is intentionally over and above the required information bits. The transmitter sends the information bits along with some extra (also known as parity) bits. The receiver uses the redundant...
system using a Reed-Solomon code or related code of degree d-1 for detection and correction of a plurality of errors in a codeword of n symbols comprised of k data symbols and d-1 check symbols, wherein each symbol is comprised of m binary bits of information, said decoder comprising: ...
FIG. 2 illustrates a functional block diagram of the operation of the error detector 20. Essentially, the incoming pulse code modulated (PCM) data is received at detector 22 and 24 for detecting respectively a zero-string in adjacent octets and a single logic "one" in adjacent octets, and ...
