Error detection and correction

To clean up transmission errors introduced by Earth’s atmosphere (left), Goddard scientists applied Reed-Solomon error correction (right), which is commonly used in CDs and DVDs. Typical errors include missing pixels (white) and false signals (black). The white stripe indicates a brief period when transmission was paused.

Error detection and correction is about methods to make sure that information or data is not corrupted, and still makes sense. The techniques help reliable delivery of digital data over unreliable communication channels.
