Real-time Error Control Research Over Internet Communications

ABSTRACT

With the development of computer technology and Internet technology, more and more real-time error control principles are implemented. Based on research of error control technology, In this thesis, we implement data packet’s coding and decoding based on Reed-Solomon code through looking chart; and emulate the real-time error control systems that use error control methods of FEC and FEC/ARQ. Experiments results prove that coding and decoding based on Reed- Solomon code through looking chart can improve the efficiency of coding and decoding, and experiments results also validate the FEC and FEC/ ARQ error control methods, that are based on the Reed-Solomon code, have fine characteristics and fine real-time, and decrease the code error ratio by 5 % at least, at the same time, develop the data reliability and satisfy the QoS constraints.
