Abstract


Digital microwave communication system compared to the traditional cable communication , build a low cost , high reliability of information transmission , the domestic and foreign scholars in recent decades has been concerned about . With the continuous advancement of social development , science and technology , digital communication , digital broadcasting and data storage systems , extensive error correction coding theory . Commonly used RS code , convolutional code and interleaver the code constitutes cascade code , and apply it to digital microwave communication system . A more detailed elaboration of the principle of encoding , and a detailed analysis of the simulation implemented on the basis of its implementation and the communication system in the RS code and convolutional code and its associated technology . RS coding distance characteristics of a good , high coding efficiency , encoding and decoding algorithms and hardware circuit has a good anti- burst interference ability , and is widely used in a variety of error control scheme inside . In this article, at home and abroad in recent years on the basis of the RS code encoding decoding algorithms and implementation , its application convolutional code and interleaved code cascade , and Matlab simulation to achieve improved error correction capability and efficiency. This cascade code mode from the the space digital communications and military field until DVDs and other civilian areas are a wide range of important applications . This paper first introduces the basic principles of digital communication system , to expounded channel coding theorem . The basic concepts of the channel coding , classification and development were introduced. Then briefly describes the overall design of the framework of digital microwave communication system , often used in digital microwave communication system then analyzes several coding key research analyzes the RS code , convolutional the interleaved encoding and decoding algorithm . Then RS, convolutional , the interleaving encoding and decoding the principle and algorithm of the Matlab simulation to achieve . Final design of a a cascading codec based on the digital microwave communication system design , and in the last chapter of the RS code and convolutional code codec FPGA implementations .
