摘　　要：将通信新技术引进教学,设计了我校信息工程专业通信系统综合实验的拓展内容——Chirp-UWB通信系统综合实验。运用Matlab/Simulink构建了ChirpUWB系统仿真模型,实现了二进制正交键控(BOK)调制发送、以及两种接收方案包括匹配滤波器接收和锁相环接收的整个系统仿真,并比较了两种接收方案的性能,给出了在AWGN信道中误码率仿真曲线。实践表明,该综合实验加强了学生对通信系统原理的理解,提高了综合运用所学知识解决实际问题的能力。Chirp-UWB communication system comprehensive experiment is designed by introducing the new communication technology to teaching. This is the communication system of information engineering and extends the comprehensive experiment content. Chirp-UWB system simulation model is constructed based on Matlab / Simulink. BOK modulation signal is realized. The system can simulate the matched filter receiver and phase-locked loop receiver.Finally,the performance of the two receiving schemes is compared,and the SNR-BER simulation curves are given in the AWGN channel. Practice shows that the integrated experiment strengthens the students＇ understanding of communication system and enhances the ability by using the comprehensive knowledge to solve practical problems.
