What are the different types of error-correcting codes?

Error-correcting codes are techniques used to detect and correct errors in data transmission. The main types include Hamming codes, Reed-Solomon codes, and convolutional codes.

Can you explain Hamming codes?

Hamming codes are a set of error-correcting codes that can detect up to two-bit errors and correct one-bit errors. They work by adding redundant bits to the data.

What about Reed-Solomon codes?

Reed-Solomon codes are widely used in digital communications and storage. They can correct multiple symbol errors and are particularly effective in burst error correction.

How do convolutional codes work?

Convolutional codes work by encoding data streams using a sliding window approach, allowing for real-time error correction during transmission.

Which type is the most commonly used?

Reed-Solomon codes are among the most commonly used, especially in applications like CDs, DVDs, and QR codes.
