Abstract :
In order to meet both the dynamic qualities and the acquisition accuracy of multi-mode receiver, this paper gives a variable sampling FFT+PMF Fast Acquisition method on the basis of analyzing the every system signals´ characteristics and related technologies. Combine with DSP+FPGA, it forms a hardware platform, gives part of the capture program and DSP capture process.
