Enhance Orthogonal Code Convolution Capabilities for Efficient Digital Communication

Real time transmission of data at high bit rates is one of the increasing demands today. This has inadvertently made data susceptible to noise resulting in impairment during transmission. In this paper, Orthogonal Codes have been developed and realized using Xilinx software for efficient digital communication for not only can they detect and correct errors but also do away with the requirement to send the parity bit. The result shows that the proposed technique enhances the error detection capabilities of orthogonal code convolution from 50% to 99.99% for 32 bit orthogonal code and corrects up to (n/4-1) bits of error in the received impaired code. Key-words: Orthogonal Codes, Antipodal Codes, Error Detection and Correction.
