Block Codes

Block codes are a method used in digital communication to detect and correct errors in data transmission. Data is divided into fixed-size blocks, and each block is transformed with additional check bits using a specific algorithm. These check bits help the receiver identify and fix errors that may occur during transmission over noisy channels. Essentially, block codes improve the reliability of data transfer by ensuring that the original message can be recovered accurately, even if some parts are altered or lost along the way.
