摘要
为满足宽带卫星通信实验教学及科研项目需求,设计了一套基于Hollis的宽带实时卫星信道模拟平台。该平台由可编程调制器、信道模拟器、可编程解调器等构成,能够较好地程度模拟卫星信道传输特性(信号传输时间长、多普勒变化、噪声等)。通过该平台学习,学生能够根据直观、深刻理解卫星信号的传输及信号处理理论,并能够使用可编程器件(FPGA)进行调制、解调器进行算法验证,在提高卫星通信教学实验质量同时为宽带卫星科研项目提供有力的支持。
To satisfy the requirements of experiment teaching and research for wide-band satellite communication, a wide-band and real-time satellite channel simulator based on Hollis is designed. This simulator consists of programmable modulator/demodulator, Hollis device which provides good performance to simulator the satellite＇ s main features, such as long transmission time, Doppler changes, and noise. This platform with high capacity FPGA device on board not only gives a better way for students to understand the fundamental satellite signal transmission and processing, but also is great helpful to do the satellite communication research project.
