The Research And Realization Of Wireless Data Modulation Based On DSP/PCI Interface

As one of the most important mode in communication system, wireless communication has been got widely attention. The development of new technology accelerates the progress of wireless communication. Along with the rapid growth of VLSI technology and computer technology, DSP has been used widely in communications areas. In this paper, a wireless data modulation system based on DSP/PCI interface board are studied and implemented.Based on the characteristic of wireless communication system, the paper chooses proper coding and modulation mode, completed the design and debug of DSP target board based on the PCI slot of computer and realized data wireless transfer. In the paper, the followings are the pivotal points:1 the realization of data transfer through PCI bus of computer and HPI interface of DSP2 the realization of modulation with DSP based on DDS3 the realization of code with computer4 design BOOTLOADER of DSP5 program PCI interface board driverThe significance of the paper is that it adopts the advanced digital technology to realize data transfer between DSP and computer and complete the modulation through DSP. The key technology of the paper(including data transfers between DSP and computer, modulation with DSP based on DDS , BOOTLOADER designed myself, etc)is relatively new and worth a deep research..
