Implementation of error trapping technique in (31,16) cyclic codes for two-bit error correction in 16-bit sound data using Labview Software

This paper considers the implementation of cyclic codes encoder and decoder for multimedia content in the form of sound data using National Instruments LabView software. Cyclic codes can be defined by two parameters, which are code size n and information bit size k. LabView is an easy to use, multipurpose software which has many features for designing and prototyping. This research is a preliminary research on channel coding implementation on LabView. In this research, cyclic codes are used to implement the design. 16-bit sound data are used as test subjects for cyclic code encoding, decoding, and error correction. The result shows that the design works well. The design can correct short two-bit error in last n-k position of the codeword. Authors' next project is to implement more advanced code for error correcting implementation in LabView.
