摘　　要：研究了基于软件无线电的MSK调制系统。MSK是一种典型的恒包络调制技术,有相位连续和频带利用率比较高等优点。分析了软件无线电中上变频理论、正交调制原理、NCO原理和MSK调制。利用System Generator软件对软件无线电中的MSK进行了仿真,并对仿真结果进行了分析和总结,证明此调制系统具有良好的调制性能,此方法正确、可行。MSK modulation system based on software radio is studied. MSK is a typical kind of constant envelope modulation technique,having advantages of continuous phase and high efficiency of bandwidth, etc. The theory of up-conversion, the principles of quadrature modulation and NCO and MSK modulation in software radio are analyzed. The MSK in software radio is simulated using System Generator,and the results are analyzes and summarized. The good performance of the modulation system proves the validity of the method.
