软件定义无线电matlab源代码使用深度学习架构的无线电调制分类 添加一名作者 该笔记本包含我在 2020/2021 学年的代码。 抽象的 学士学位论文的重点是使用深度学习方法进行无线电调制分类。 论文中提出了四种深度学习架构。 其中三个使用卷积和循环神经网络，第四个使用变压器架构。 在设计阶段考虑了每个模型的最终参数数量，因为它会对部署模型的内存占用产生很大影响。 这些架构是用 Keras 编写的，这是一个软件库，为神经网络提供 Python 接口。网络。 此外，还将这些架构的结果与有关该主题的其他研究论文的结果进行了比较。 代码结构如下： 导入- 导入所需的库 定义的函数-定义函数以便以后更容易地处理数据 访问数据集- 如果您愿意，您可以跳过这一部分并在其他地方下载数据集 加载数据- 加载数据并将它们划分为训练、验证和测试集 深度学习部分- 包含准备进行训练和评估的架构 加载训练模型- 您可以选择下载 CGDNN 模型并查看它在相应数据集上的表现 层可视化- 为可视化卷积层和循环层的激活图而编写的一部分代码 绘图- 您可以在这部分绘制混淆矩阵 这段代码在 Google Colab

Thoroughly revised and updated, this second edition offers a fundamental and comprehensive treatment of how mobile systems operate in a variety of scenarios. This unrivalled approach concentrates on the properties of the radio channel, a vital and central feature that places fundamental limitations on the performance of radio systems. Bringing the reader completely up-to-date, this book: * Features two new chapters: 'Multipath Mitigation Techniques' and 'Radio System Planning' * Surveys various alternative methods of predicting the mean signal strength and its variability, and discusses their applications * Introduces ray-tracing methods in connection with indoor propagation * Discusses multipath and its effects on narrowband and wideband systems * Describes channel sounders and reviews methods of hardware and software simulation * Examines man-made noise and interference and discusses the resulting performance degradation By equipping the reader with a thorough understanding of the physical processes that underlie the propagation of radio waves, this systematic approach will prove to be an authoritative and attractive text for researchers, systems designers, university academics and postgraduate students.

09年新书，很好的知无线电 网络中的频谱接入和管理，下面是IEEE的书评： The book is divided into three parts. Part one is a general introduction to wire- less communication systems, reviewing communication architectures and tech- nologies, as well as resource allocation protocols and dynamic spectrum access, discussing features, research challenges, and standardization. Part two is a further discussion on wireless system design with a focus on analysis of dynamic spectrum access systems. A brief introduction to signal processing and optimization tech- niques is presented, as well as basics of game theory and intelligent algorithms (e.g., machine learning, genetic algo- rithms, and fuzzy logic). Finally, part three discusses in detail dynamic spec- trum access and management. Models and architectures of dynamic spectrum access are introduced and described in detail. The authors first present the cen- tralized dynamic spectrum access model, and later focus on the distributed approach. Distributed dynamic spectrum access is discussed from the algorithmic and protocol perspectives in separate chapters. Finally, a spectrum trading model is presented with its applications to wireless communications. This book is a valuable source of information for people new to the con- cept of dynamic spectrum access. Also, scientists and engineers already involved in dynamic spectrum access research will find this book a good reference source. This is one of the few books on the mar- ket related to dynamic spectrum access and cognitive radio written completely by the authors themselves. Therefore, it is very cohesive, has a very good flow, and does not repeat itself while intro- ducing new concepts, as do many edited books on a similar topic available on the market. Many concepts of dynamic spec- trum access are well systematized in the book, and the literature review is very broad and complete. One small draw- back is a bit too lengthy introduction to wireless communication systems in part two of the book (which can e
