| This project is on-line automatic recognition of the satellite signal modulation mode. It accomplishs a general signal analysis system based on the theory of softwareradio. This paper particularly describs the satellite signal auto recognition subsystem . To recognise the signal ,the subsystem must sample the signals .process them .obtain the characters,and classify them. The basic theories applied to this project are researched and the key techniques of carrier calculation,characters counting,and mode recognition are described .Because there are many practical problems involved in the project,the method of evaluation and the evaluation are given by engineeringrule. |
