Abstract: In modern communication system, multimedia contents in digital form are used to transmit the information. Probability of error is higher during this transmission which will affect the extraction of data. This paper considers the implementation of cyclic codes encoder and decoder for multimedia contents 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 user-friendly software which has many features for designing and prototyping. This project is based on channel coding implementation using cyclic codes in LabView. 16- bit sound data are used as test subjects for cyclic code encoding, decoding and error correction. The design can correct two-bit error in last n-k positions of the codeword. The design can correct short twobit error in last n-k position of the codeword.
