Information on Error Detection and Correction

A critical aspect in data transmission is the determination of whether the received data is error-free. To do this some form of error protection, or error detection and correction is utilised. The numbers of errors at the output of the receiver can be reduced by adding additional information to the message to increase the receiver’s decision-making ability. This additional, redundant information increases the overhead that is included in the transmission.


Other topics in our resources on Communications Systems related to Error detection and correction include: 
 
  • Forward Error Correction (FEC)
  • Error detecting code (EDC)
  • Cyclic redundancy check (CRC)

  • Block code
  • Automatic repeat request (ARQ)

  • Cyclic code
  • Frame check sequence (FCS)
  • Convolutional code
