Error Checking and Correction
Error Separation and Correction (ESC) codes are used in data communication systems to detect and correct errors that may occur during transmission. These codes are typically added to the transmitted data at the sender's end and then decoded at the receiver's end to check for errors.
ESC codes are designed to detect and correct errors that occur during transmission, such as bit flips caused by noise or interference. There are two types of ESC codes: error detection codes and error correction codes.
Error detection codes are used to detect errors during transmission. They are typically added to the transmitted data as a parity bit, checksum, or cyclic redundancy check (CRC). When the data is received at the other end, the receiver calculates the parity, checksum, or CRC and compares it to the one sent by the sender. If they do not match, an error is detected.
Error correction codes, on the other hand, are used to detect and correct errors during transmission. These codes are typically more complex than error detection codes and can correct errors up to a certain number of bits. Popular error correction codes include Hamming codes, Reed-Solomon codes, and Turbo codes.
Overall, ESC codes are an important aspect of data communication systems as they help ensure the accuracy and reliability of transmitted data.
