A Review for Error Control Capabilities using Orthogonal Code Convolution

Information and communication technology has brought enormous changes to our life. With the increase of data transmission and hence source of noise and interference, engineers have been struggling with the demand for more efficient and reliable techniques for detecting and correcting errors in received data. Although several techniques and approaches have been proposed and applied in the last decade, data reliability in transmission is still a problem. Error detection and correction techniques are therefore required. Among other techniques such as Cyclic Redundancy Check and Solomon Codes; orthogonal coding is one of the codes which can detect errors and correct corrupted data in an efficient way. An n-bit orthogonal code has n/2 1s and n/2 0s. In a previous work these properties have been exploited to detect and correct errors. In this review paper we discussed a new methodology to enhance error detection capabilities of the orthogonal code.
