When data is stored, compressed, or communicated through a media such as cable or air, sources of noise and other parameters such as EMI, crosstalk, and distance can considerably affect the reliability of these data. Error detection and correction techniques are therefore required. Some of those techniques can only detect errors, such as the Cyclic Redundancy Check (CRC); others are designed to detect as well as correct errors, such as Solomon Codes, Hamming Codes, and Orthogonal Codes Convolution (OCC). However, the existing techniques are not able to achieve high efficiency and to meet bandwidth requirements especially with the increase in the quantity of data transmitted. Orthogonal Code is one of the codes that can detect errors and correct corrupted data.
