入门GNU_Radio＋USRP很好的中文资料，有基础的可以在一天内入门上手。

GNU广播USRP AoA GNU Radio软件包实现了MUSIC和根MUSIC到达角算法，并带有提供USRP设备相位同步所必需的模块。 这是的更新和改进版本。 已实现的块： 示例性GR GUI： 安装步骤： cd git clone https://github.com/MarcinWachowiak/GNU-Radio-USRP-Beamforming cd GNU-Radio-USRP-Beamforming/gr-aoa mkdir build cd build cmake .. make -j$(nproc) sudo make install sudo ldconfig 该存储库还包含MUSIC算法的仿真和以Python实现的参数分析。 示范性仿真结果：

GNU Radio是一个免费的开源软件开发工具包，它提供信号处理模块来实现软件无线电。 它可以与现成的低成本外部RF硬件一起使用，以创建软件定义的无线电，或者在类似仿真的环境中不使用硬件。 它被广泛用于业余爱好者，学术和商业环境，以支持无线通信研究和现实世界的无线电系统。 请访问GNU广播网站和Wiki 。 在GitHub的上跟踪错误和功能请求。 如果您对GNU Radio存有疑问，请搜索describe-gnuradio邮件列表，因为许多问题已经被提出并回答。 请同时邮件列表，并在此处发布您的新问题。 如何安装GNU Radio 预建的二进制文件 在大多数平台上安装GNU Radio的推荐方法是使用可用的二进制软件包发行版。 以下命令适用于Debian，Ubuntu和衍生产品。 它将使用Python2安装3.7版。 sudo apt install gnuradio 对于其他操作系统，请参阅 PyBOMBS PyBOMBS擅长从源代码构建GNU Radio，UHD和各种Out of Tree（OOT）模块，然后将其安装到指定的用户目录中，而不是系统文件中。 PyBOMBS会

GNU_Makefile中文手册，里面包含了所有的make的用法，不用上网去拼凑的学习

GNU make is the most widely used build automation tool, but it can be challenging to master and its terse language can be tough to parse for even experienced programmers. Those who run into difficulties face a long, involved struggle, often leaving unsolved problems behind and GNU make's vast potential untapped. The GNU Make Book demystifies GNU make and shows you how to use its best features. You'll find a fast, thorough rundown of the basics of variables, rules, targets, and makefiles. Learn how to fix wastefully long build times and other common problems, and gain insight into more advanced capabilities, such as complex pattern rules. With this utterly pragmatic manual and cookbook, you'll make rapid progress toward becoming a more effective user. GNU make is known for being tricky to use, but it doesn't have to be. If you're looking for a deeper understanding of this indispensable tool, you'll find The GNU Make Book to be an indispensable guide.

很详细的make使用说明，叫你如何编写makefile文件，makefile关系到了整个工程的编译规则。一个工程中的源文件不计数，其按类抄型、功能、模块分别放在若干个目录中，makefile定义了一系列的规则来指定，哪些文件袭需要先编译，哪些文件需要后编译，哪些文件需要重新编译，甚至于进行更复杂的功能操作，因为makefile就像一个Shell脚本一样，其中也可以执百行操作系统的命令。

gnu-assembler 1.1 Structure of this Manual This manual is intended to describe what you need to know to use gnu as. We cover the syntax expected in source files, including notation for symbols, constants, and expressions; the directives that as understands; and of course how to invoke as. This manual also describes some of the machine-dependent features of various flavors of the assembler. On the other hand, this manual is not intended as an introduction to programming in assembly language—let alone programming in general! In a similar vein, we make no attempt to introduce the machine architecture; we do not describe the instruction set, standard mnemonics, registers or addressing modes that are standard to a particular archi- tecture. You may want to consult the manufacturer’s machine architecture manual for this information. 1.2 The GNU Assembler gnu as is really a family of assemblers. If you use (or have used) the gnu assembler on one architecture, you should find a fairly similar environment when you use it on another architecture. Each version has much in common with the others, including object file formats, most assembler directives (often called pseudo-ops) and assembler syntax. as is primarily intended to assemble the output of the gnu C compiler gcc for use by the linker ld. Nevertheless, we’ve tried to make as assemble correctly everything that other assemblers for the same machine would assemble. Any exceptions are documented explicitly
