摘要
原有的差分跳频同步算法容易导致频点误判,基于此提出了一种改进的同步算法。详细介绍了其基于FPGA的硬件实现方案,并采用DSP BUILDER进行了硬件仿真,给出了仿真时序波形。经测试,该同步方案具有速度快、同步准确度高、计算周期短等特点,在差分跳频同步系统中具有广阔的应用前景。
On the basis of original DFH synchronization algorithm,this paper proposes an improved synchronization algorithm.Its implementation on FPGA is introduced.Hardware simulation is realized by DSP BUILDER software in Matlab/Simulink environment.VHDL language is used for wave simulation.After test,this scheme has the faster synchronization speed,better synchronization precision and less calculate time,which could be widely used in many areas.
