摘要
结合我校通信电子电路、通信原理、现代通信系统等课程,设计了信息工程专业通信系统综合实验的一个拓展内容———超宽带通信同步跟踪系统仿真实验。本仿真实验在Simulink平台下,基于超前-滞后锁相环搭建了超宽带通信同步跟踪系统。该系统在单用户状态下,选用PPM调制方式、AWGN信道传输,实现了在加性高斯白噪声信道下点对点的通信,成功反映了PPM调制方式的特点,完成了脉冲超宽带(IR-UWB)信号的同步跟踪。在Simulink建模过程中,利用既有模块与Sfunction编程设计相结合完成了系统仿真,并使同步误差函数值可视化,充分说明该系统的优越性。
Combined with school＇s courses,such as communication electronic circuit,communication theory,modern communication systems and so on,we designed an expanding content of communication systemic comprehensive experiment about information engineering. It can complete the simulation experiment of UWB synchronization tracking system. This simulation is based on the lead-lag phase-locked loop to build UWB synchronization tracking system,under the platform of Simulink. In single-user mode,the choice of the PPM modulation,the AWGN channel transmission,the system achieves a point-to-point communication under the additive white Gaussian noise channel,succeeds reflecting the characteristics of the PPM modulation mode,and completes the pulse ultra-wideband（ IR-UWB） signal synchronization tracking. In modeling process of the Simulink,using the existing modules and S-function programming the designing system completes system simulation,and made the synchronization error function value visualization,which shows the superiority of the system.
