超宽带脉冲信号调制方式的研究及Matlab实现(任务书,开题报告,论文12000字)
摘  要   
超宽带早期作为美国军方大力研究的前沿通信技术，2002年由美国FCC批准进入民用领域，并制定超宽带技术的标准，至今已有近二十年的时间，超宽带技术却仍未在日常生活中得到广泛的应用，本文通过研究超宽带技术中脉冲调制方式，来加深对这种技术的理解，并通过对超宽带技术基本概念与发展历程的研究，更直观地去把握超宽带技术未来的发展走向。
本文对超宽带信号调制方式中的IR-UWB(脉冲调制超宽带方式)的原理进行了深入研究的基础上，着重讨论了超宽带脉冲调制技术的功率谱，并对每种脉冲调制方式进行了仿真。最后，通过对比三种调制方式，发现了各调制方式的特色，并对每个调制方式的优缺点进行了分析。
论文主要研究了多种不同的超宽带脉冲调制方式的原理、功耗，并对每种方式做了基于Matlab和simulink的仿真。
研究结果表明：超宽带脉冲调制方式的不同，调制出的信号的性能也各有特点。
关键词：超宽带；脉冲调制；功率谱；同频带干扰

Abstract
UWB was used as the forefront communication technology that the U.S. military vigorously studied. It was approved by the U.S. FCC to enter the civilian field in 2002, and it has established ultra-wideband technology standards. For nearly two decades, UWB technology is still not in everyday use. It has been widely used in life. This paper studies the pulse modulation method in UWB technology to deepen the understanding of this technology, and through the study of the basic concepts and development history of UWB technology, to more intuitively grasp the future of UWB technology. The direction of development.
In this paper, the principle of IR-UWB (Ultra-wideband with pulse modulation) in the UWB signal modulation method is studied in detail. The power spectrum of UWB pulse modulation technology is discussed in detail, and each pulse modulation method is performed. simulation. Finally, by comparing the three modulation methods, the characteristics of each modulation method are discovered, and the advantages and disadvantages of each modulation method are analyzed.
The dissertation mainly studies the principle and power consumption of many different UWB pulse modulation methods, and simulations based on Matlab and simulink are made for each method.
The result of the research shows that the performance of the modulated signal is different from that of the UWB pulse modulation method.
Key Words：Ultra-wideband；Pulse modulation；power spectrum；frequency band interference
