Open publisher page 0 citations

Abstract

This design of frequency modulation modulator based on DSP uses SDR.The system hardware partially takes the TMS320VC5402 Digital Signal Processor(DSP) as a core,and uses Host Port Interface(HPI) and PC real-time communication.Software is composed by the DSP algorithm procedure and the host user program,the DSP algorithm procedure responsibly completes the signal modulation and so on the real-time processing,the host user program responsibly completes to DSP the control and the correspondence as well as the user interactive.This system has fully displayed the PC flexibility and the DSP high speed realtime processing ability.
