摘要
MSK作为一种性能优良的调制方式,被广泛应用于卫星通信和无线移动通信中的数据传输。串行MSK调制多用于数据速率较高的场合,在工程实现上有着较为广泛的应用。简要分析了基于带通滤波器和基于低通滤波器的两种MSK串行调制与解调方式,利用通信系统仿真软件System View,对两种调制与解调方式进行了仿真,给出了详细的仿真电路,并通过仿真分析了不同干扰条件下的抗干扰性能。
MSK is widely used in the data transmission of satellite communications and wireless mobile communication because of its excellent performance. Serial rusk modulation and demodulation is used in the higher data rate and the application of engineering. The techniques of serial MSK modulation and demodulation based on bandpass filter and lowpass filter are discussed. The simulation of serial MSK modulation and demodulation based on SystemView is performed and the detailed simulation circuit is given. The simulation results of anti-jamming in the various jamming signal is given.
