This document describes an FPGA implementation of orthogonal codes for efficient digital communication. Orthogonal codes contain an equal number of 1s and 0s and can detect errors without needing to transmit parity bits. The authors implement an orthogonal code error detection and correction system on an FPGA using VHDL. Simulation results show the technique can detect up to 99.99% of errors and correct up to half the code length minus one bit errors for an n-bit orthogonal code. Compared to other techniques like CRC and Hamming codes, orthogonal codes provide higher error detection and correction capabilities.
