Channel coding is a technique used in communication systems to add redundancy to transmitted information, enabling error detection and correction in the presence of noise and interference. It enhances the reliability of data transmission over noisy channels, ensuring that the original information can be accurately reconstructed at the receiver end.

Redundancy refers to the inclusion of extra components or information that are not strictly necessary, often to ensure reliability and fault tolerance. It is a crucial concept in various fields, from engineering and computing to linguistics and organizational design, where it helps prevent system failures and enhances communication clarity.

Error correction is a process used to detect and correct errors in data transmission or storage, ensuring data integrity and reliability. It employs algorithms and techniques to identify discrepancies and restore the original data without needing retransmission.

Error Correction

Noise and interference are critical factors that degrade the quality and clarity of signals in communication systems, often resulting in data loss or errors. Understanding and mitigating these effects is essential for improving the reliability and efficiency of data transmission across various media.
