摘要
对无线移动通信中广泛应用的调制方式—高斯最小频移键控(GMSK)做了详细的研究。分析了高斯最小频移键控的理论,给出了高斯最小频移键控调制和解调的工作原理,并且基于动态系统仿真软件SystemView对该系统进行了计算机仿真。在此基础上,利用SystemView提供的分析工具就高斯最小频移键控的功率谱密度和抗噪声性能和最小频移键控(MSK)做了对比分析,得出了一般结论。
In this paper, we discuses the principle of GMSK modulation and demodulation in detail and give the structure of GMSK modulation and demodulation system. Then we build a simulation structure by a software ＂system view＂ released by Elanix Ltd. At last, we discuss the performance of GMSK in respect of power spectrum density and bit error rate and compare the result with MSK system.
