  • Channel Coding Theory

    765 Words  | 4 Pages

    There are two classes of codes, Source coding and Channel coding: Source coding attempts to compress the data from a source in order to transmit it more efficiently. This is commonly used on the Internet. Channel coding adds extra data bits, commonly called parity bits, to make the transmission of data more robust to disturbances present on the transmission channel. Channel Coding theorem states that since any communication channel is characterized by its channel capacity C there exist a coding method
