The platform fot TI's DSP chip TMS320VC5416 as the core to process signal for realizing digital modulation algorithms, respectively,the ADC and DAC constitute data acquisition modules and to the modulation signal processing module in the peripheral circuits,and the CPLD constitute logic control module, which provide interface control signals,and realize input information retrieval functions, decoding functions and sub-band function. In software design, it is divided into logic control and digital modulation algorithm in two parts. Part of the overall logic control realize CPLD logic control module and digital modulation part realize ASK, FSK, QPSK modulation algorithm in the DSP module.The software-defined radio platform has lots of advantages such as faster processing speed, real-time operational, large amounts of data storage and so on.
