Forney's Algorithm

Forney’s Algorithm is a method used in digital communications to efficiently decode error-correcting codes, specifically Reed-Solomon codes. When data is transmitted, errors may occur; the algorithm helps identify and correct these errors by calculating an error locator polynomial. It then determines the exact positions and values of the errors, allowing the receiver to recover the original message accurately. Essentially, Forney’s Algorithm streamlines the process of fixing multiple errors in data transmissions, ensuring reliable communication over noisy channels with minimal computational effort.
