摘要
介绍了二进制偏移载波(Binary Offset Carrier,BOC)调制信号的原理与特性,设计了一种基于FFT的BOC(15,2.5)信号快速捕获的硬件实现方案;对捕获算法和电路的整体设计流程进行了详细说明,重点介绍了核心模块和设计难点;仿真和实际电路测试表明此方案可对BOC(15,2.5)信号完成较高精度的快速捕获。
A hardware solution of acquiring the new-introduced Binary Offset Carrier（BOC） modulation signal based on FFT is proposed.The acquisition algorithm and whole design flow are explicitly presented.Core modules and key segments of the design are detailed in particular.Simulation results and hardware circuit performance show that this solution could successfully accomplish the rapid acquisition of BOC（15,2.5） signal with a relatively high accuracy.
