Reed-Solomon codes are a type of error-correcting code that work by encoding data in a way that allows for the detection and correction of errors, particularly useful in digital communications and storage. These codes are based on finite fields and polynomial interpolation, making them highly effective for correcting burst errors, which can occur when multiple adjacent symbols are corrupted. The connection to extremal combinatorics comes from the design of these codes, where combinatorial structures are utilized to maximize error correction capability while minimizing redundancy.
congrats on reading the definition of Reed-Solomon Codes. now let's actually learn it.
