摘要
分析了2FSK、MSK、GMSK这三种广泛应用的数字调制技术,在Matlab/Simulink仿真环境下对三者的调制、解调和同步模块建立了仿真模型,对三者的传输带宽以及误码率等调制性能作了对比,仿真结果表明GMSK具有更好的频谱特性和较小的误码率。
2FSK, MSK and GMSK, three widely used digital modulation technology, are analyzed and a simulation model of modulation, demodulation and synchronization is established under the Matlab/Simulink simulation environment. The simulation results, which compare the modulation property of transmission bandwidth and bit- error-rate, show that GMSK has better spectral characteristics and lower bit-error-rate.
