【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。更多还原

【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.更多还原
