摘要
根据软件无线电的设计理念,无线电解调算法需要较为灵活的解调算法构架,通过构件化的软件,可对多种不同的调制方式进行解调,使无线电的功能不再过度依赖硬件。论文根据此思路,以MSK为例进行设计并在FPGA上试验,在较为简单的硬件结构下实现了MSK解调算法。而且此算法框架可以同时适用于其他调制信号的解调,减少了硬件平台的设计和更改。适用各种传输的MSK信号的场合,为MSK信号解调的实际应用提供了参考。
According to the design concept of software radio, the radio demodulation algorithm needs a more flexible demodu- lation algorithm architecture. Through component software, many different modulation methods can be demodulated, so that the radio functions no longer rely on hardware excessively. Based on this idea, this paper designs and tests MSK as an example, and implements the MSK demodulation algorithm in a relatively simple hardware structure. Moreover, this algorithm framework can be applied to demodulation of other modulation signals at the same time. While reducing the hardware platform design and change. For a variety of transmission MSK signal occasions. It provides a reference for the practical application of MSK signal demodulation.
