Software radio technology in spread spectrum communication

摘要

Software radio as a new emerging technology has been widelynregarded. It becomes the final aim that radio realizes softwarenprocessing and controlling. With restriction of the speed of the digitalnprocessing devices, especially the bottleneck of DSP, today's researchnin software radio is mostly limited to traditional narrowband signalsn(<2 MHz). A new kind of scheme in accordance with spread spectrumncommunication is given. The scheme overcomes the bottleneck of DSP bynmeans of combination of several advanced digital processing techniques.nThis research makes a positive and useful discussion for the realizationnof software radio for military anti-jamming radio
