一种基于软件无线电思想的GMSK调制设计

GMSK在无线通信中得到了广泛的应用，是通信设备半实物仿真器生成的重要信号之一。文中针对仿真器信号源库的构建，在介绍通用通信设备半实物仿真器组成的基础上，分析了GMSK调制的设计，利用Matlab软件仿真了GMSK信号正交分量的生成。提出了一种基于软件无线电思想，在仿真器通用硬件框架下产生GMSK信号的设计方案。为通信设备半实物仿真器信号源库的构建提供了参考，也为通信设备的仿真和通信电磁环境的模拟提供了借鉴。

A GMSK design based on the thought of software defined radio

GMSK has been widely used in wireless communications. It is one of the important signals generated by the hardware-in-the-loop simulator. This paper aims at the source library building for emulator. It analyses GMSK modulation design and gives an matlab software simulation for the quadrature components generation of the GMSK signal which is based on the introduction about hardware-in-the-loop simulator construction. According to the software defined radio thought, the paper puts forward a GMSK signal generation design under the framework of the common hardware emulator. It provides a reference for the construction of signal source library and simulation of communication equipment as well as electromagnetic environment
