Forward Error Control Coding Based on Orthogonal Codes and Its Implementation Using FPGA

摘要

A method of Forward Error Correction Coding (FECC), based on orthogonal codes, has been developed and realized by means of Field Programmable Gate Array (FPGA). The proposed technique maps a k-bit data block into an n-bit bi-orthogonal code block (n>k) and transmits the coded block across the channel. Construction of rate ? and rate ? orthogonal coded modulation schemes are realized by means of FPGA. The results confirm that the proposed block coding technique can detect and correct errors with bandwidth efficiency.
