Error Correction In Software Radio And Its Dsp Implementation

The application of the software radio communication technology is more universal as the development of the microelectronics technology and digital signal process technology. It was born in military communications field first and was used in personal communications later and other electronics field. Because of the excellent secrecy and anti-jamming ability as well as agility and the ability to recombine, software Frequency-Hopping radio technology is of great importance in military domain and of great value in research and development. This work was supported by China Electronics Technology Group Corporation No.50 Institute under Project the software radio. The auther was responsible for channel error control part of the subject. The paper begins with introduce of software Frequency-Hopping radio. Subsequently, author summarizes the principle of error and correcting encodes in channel of digital communications and decides on and demonstrates. Then, several algorithms of Golay code and RS code are discussed and compared in detail. The ultimate simulated data of this subject are represented at last. Finally, it is done in dsp.
