A general analog radio signal processing platform has been built based on SWR and DSP techniques. Key algorithms of IF passband sampling, modulation pattern recognition have analysed in detail. Analysis methods of real time radio signal used in different bands and in different modulation schemes have also been presented. Finally, statistic results of system simulation are given.
