自适应天线的matlab仿真代码卫星通信系统项目 在这个项目中,我学习了如何按照最新的数字视频广播–卫星DVB-S2标准来计划,实施,分析和模拟卫星通信系统。 该项目包括五个部分。 第一部分涉及链路预算计算,确定信噪比(SNR)以满足一定的性能要求。 第二部分涉及DVB-S2标准的基带仿真。 第三部分旨在模拟DVB-S2X非恒定包络调制方案,该方案在MATLAB中不可用。 第四部分的目的是在卫星转发器上开发一种自适应编码方案,该方案将传输参数调整到终端的接收条件,例如在下雨时切换到较低的编码率。 第五部分通过在客户场所的接收器处使用多个天线来改进和实现分集以及组合技术,以改善卫星信号的传输。 * DVB-S2调制器发射机框图:

Wireless Optical Communication Systems addresses the problem of designing efficient signalling and provides a link between the areas of communication theory and modem design for amplitude constrained linear optical intensity channel. Topics include historical perspective, channel impairments, amplitude constraints and the characteristics of popular optoelectronic components. A variety of wireless optical channel topologies are presented along with a survey and analysis of present day signalling techniques employed for these channels. The author provides a unifying framework for signalling design which allows the channel constraints to be represented geometrically and permits the use of modem design principles from electrical channels. Modulation schemes are designed using the formalism of lattice codes and a design process for signalling sets is specified.

Preface The field of digital communication has evolved rapidly in the past few decades, with commercial applications proliferating in wireline communication networks (e.g., digital subscriber loop, cable, fiber optics), wireless communication (e.g., cell phones and wireless local area networks), and storage media (e.g., compact discs, hard drives). The typical undergraduate and graduate student is drawn to the field because of these applications, but is often intimidated by the mathematical background necessary to understand communication theory. A good lecturer in digital communication alleviates this fear by means of examples, and covers only the concepts that directly impact the applications being studied. The purpose of this text is to provide such a lecture style exposition to provide an accessible, yet rigorous, introduction to the subject of digital communication. This book is also suitable for self-study by practitioners who wish to brush up on fundamental concepts. The book can be used as a basis for one course, or a two course sequence, in digital communication. The following topics are covered: complex baseband representation of signals and noise (and its relation to modern transceiver implementation); modulation (emphasizing linear modulation); demodulation (starting from detection theory basics); communication over dispersive channels, including equalization and multicarrier modulation; computation of performance benchmarks using information theory; basics of modern coding strategies (including convolutional codes and turbo-like codes); and introduction to wireless communication. The choice of material reflects my personal bias, but the concepts covered represent a large subset of the tricks of the trade. A student who masters the material here, therefore, should be well equipped for research or cutting edge development in communication systems, and should have the fundamental grounding and sophistication needed to explore topics in further detail using
