| Abstract: | This paper introduced a theory and implementation method of a new type of sonde receiver design which is based on software radio.It primarily studies the IF disposal part with digital signal processor as the core and has proposed the demodulation scheme of sonde signal.It achieved the Matlab simulation of the FIR low-pass filter design in DDC and the base band signal demodulation.The flexibility,practicality and expansibility of this software radio receiver are better than the present ones. |
