The Software radio is the third breakthrough in wireless communications after the following analog communica-tions to digital communications, fixed communications to mobile communications. Modulation and demodulation techniques in software radio systems occupy a very important position, and its pros and cons of the performance of the system is the key for the software radio. The modulation algorithm for software radio architecture with matalab AM, FM, 2FSK signal modulation al-gorithm, and on this basis carried out simulation, thus proved that the correctness of and feasibility of the algorithm.
