摘要
介绍了扩频通信中的跳频技术和GMSK采用跳频技术的原理,利用Matlab中的Simulink通信工具箱模拟仿真GMSK跳频信号的调制与解调过程,设计出一种GMSK跳频通信系统,并对其组成的通信系统进行结构分析和测试结果说明。测试结果表明,该系统在没有信道干扰条件下得到了较理想的调制解调以及跳频传输波形图,并且误码率为零。
Both spread spectrum communication technology and GMSK with frequency-hopping technology were introduced.Through Simulink toolbox in Matlab,the GMSK frequency-hopping communication mod/demod process was simulated and its structure was analyzed.The results show that this system has ideal mod/demod waveform and zero error in the absence of channel interference.
