| Abstract: | The thought of the software wireless has already expanded into wireless correspondence realm. That technique depends on hardware technique of wide band and even antenna,high speed AD/DA chip,an array of programmable large -scale logic,the high speed DSP numerical signal processing chip, And realization of AM modulation and demodulation are introduced, the main programming of AM modulation and demodulation algorithm based on TMS320C32DSP chip is given. Through the test that software desizn revolves on the software radio hardware platform,various function index signs of system all attain the request of design, |
