Based on analyzing the theory of encoding and decoding of cyclic code, this paper showed the schemes of encoding and decoding of （24,16）cyclic code by the software and based on microcontroller. Simulation results show that using （24,16） cyclic codes can effectively overcome the interference from communication channel, ensure the reliability and stability of data communication systems, and reduce the bit error rate greatly. The results of this paper show that by using the （24,16） cyclic code, the error rate can be reduced and the system throughput can be improved. Meanwhile, the system only needs to enlarge limited storage space and computation the complexity at the receiving end to realize error correction. Thus the （24,16） cyclic code has a practical value.
