FERNANDEZ, Washington  y  HERMAN, Krzysztof. Two-dimensional cyclic code with synchronization property for channels with class A noise. Ingeniare. Rev. chil. ing. [online]. 2020, vol.28, n.1, pp.16-23. ISSN 0718-3305.  http://dx.doi.org/10.4067/S0718-33052020000100016.

This article designs a new two-dimensional cyclic code that corrects burst errors, also detects and corrects slip errors. One of the characteristic of Class A noise is that it consists of a burst noise which affects several consecutive bits plus a Gaussian noise. This paper proposes a two-dimensional code that allows you to accomplish two tasks one to decrease the burst noise and the other to decrease the synchronization error that occurs when there is a bit slip and the receiver retrieves the information with error. To evaluate performance, a channel with a Class A noise is simulated. The reason signal to noise versus the probability of bit error is plotted, for different two-dimensional cyclic code size and is compared with one-dimensional cyclic code. According to the results obtained this code improves the reliability of the communication system when it is transmitted by a noise-Class A channel, significantly reducing the probability of bit error and slip error. The research is open for the construction of new two-dimensional codes that allow decreasing the probability of burst error and the error of synchronization.

Palabras clave : Two dimensional cyclic code; synchronization; class A noise.
