What is the communication error correction?

Communication error correction refers to techniques used to detect and correct errors that occur during data transmission. These methods ensure that the information received is accurate and reliable, despite potential disturbances like noise or interference. Common error correction techniques include Forward Error Correction (FEC), where redundant data is added, and Automatic Repeat reQuest (ARQ), which requests retransmission of corrupted data. By employing these strategies, systems can maintain data integrity and improve overall communication reliability.
