Abstract

In order to realize the flexibility, openness and scalability of the modem technology, the modulation and demodulation system based on DSP software radio digital technology is researched in this paper. This system realizes the modulation and demodulation algorithm of FSK, QPSK, and QAM etc. on the radio software platform which takes TMS320C6711 as the core. And The selection of the modulation and demodulation modes and the display of measured data can be real-time operated by using the virtual platform. The performance of this system is observed and analyzed by taking QPSK as a example.
