Error-detecting Codes

Error-detecting codes are codes that are designed to detect errors that may occur during the transmission of data. These codes are used in space and astronautical engineering to ensure the accuracy and reliability of data transmitted between spacecraft and ground stations. Error-detecting codes work by adding extra bits to the data being transmitted, which are used to check for errors when the data is received. If an error is detected, the receiver can request that the data be retransmitted. There are several types of error-detecting codes, including parity codes, cyclic redundancy codes (CRC), and checksums. Parity codes are the simplest type of error-detecting code and work by adding an extra bit to each byte of data. CRC codes are more complex and use a polynomial division algorithm to generate a checksum that is added to the data. Checksums are similar to CRC codes but are simpler and less reliable.
