Used in satellite and mobile communications (3G/4G) to correct errors in real-time.

These involve adding "parity bits" to a block of data.

Finding a reliable PDF or comprehensive overview of can be a challenge for students and professionals. This subject forms the bedrock of modern digital communication, bridging the gap between raw data and efficient, reliable transmission.

5G utilizes advanced Polar Codes and LDPC (Low-Density Parity-Check) codes to reach gigabit speeds.
