- By making use of the merit of portability of DSP platform, a wireless data transmission platform based on DSP is designed. The design idea, hardware structure of system platform and main program flow of algorithm are described. This system achieves conversion between modulated carrier signal and 550 MHz UHF signal using PLL and mixer, and realizes 2FSK modulation and demodulation algorithm of base band signal based on the principle of lookup-table and non-coherent demodulation. When DSP works at 160 MHz, the demodulation time for one binary element is 3 [is, which meets the requirements of system. Test shows that the system runs stably.
