| 摘 要： | GPS系统中提出了一种新的信号形式,二进制偏移载波(BOC)调制是这种新的信号形式产生的技术关键。首先介绍了BOC调制的定义及其频谱特性,然后阐述了基于FPGA(现场可编程门阵列)硬件平台的BOC调制实现方法,并给出了仿真波形。结果表明,该实现方法是值得提倡的。

| Abstract: | Binary offset carrier(BOC)modulation is the key to the new signal form which has been put forward for GPS.In this paper,the definition and spectrum character of BOC modulation are introduced firstly;then a method of implementing BOC modulation based on FPGA(field programmable gate array)hardware platform is presented and the simulation waveform is given.The results indicate that this implementation method is worth advocating. |
