MR中4FSK调制解调技术的研究及性能分析
the Research and Analysis of the Performance of 4FSK Modulation& Demodulation in the DMR System
MR协议是欧洲电信标准协会(ETSI)于2004年所提出的一种新型的数字集群通信协议，具有很好的发展前途。本文的研究重点分析了数字对讲机系统的发展现状及前景,并对DMR中物理层的4FSK调制解调部分用MATLAB进行了仿真实现。并将其通过高斯白噪声信道，分析了该系统的性能。统计计算了该实现方案的误码率,给出了程序产生的一些必要的图表。
he DMR protocol is a new digital telecommunication protocol proposed by ETSI in 2004, and have a bright future. In this paper, the current situation and the future development of the DMR is analyzed and the 4FSK modulation and demodulation of it is simulated by MATLAB. Suppose the transfer channel is an AWGN channel. The performance of this system is analyzed by calculating the BER.
