面向工程师的软件定义无线电
Software-Defined Radio for Engineers [pdf]
2018 — 2025,它一次次回到首页
黑点是上首页(≥ 50 分)的那次投稿,空心点是没冲上去的投稿,点越大分数越高。
导读
这是 Analog Devices 免费发布的《面向工程师的软件定义无线电(SDR)》教材 PDF,由 Travis F. Collins 等人撰写,涵盖从射频硬件、DSP 到通信系统的多层知识,并配有实验、习题和讲义等补充材料。它面向想系统入门 SDR 的工程师。
为什么经久不衰:SDR 横跨射频、DSP、FPGA、软件等多个领域,这本免费且经过时间检验的教材至今仍是系统入门的最佳起点之一。

SDR 是横跨射频、DSP、FPGA、软件等多学科的深坑,学习曲线层层递进。
SDR 的难点和魅力在于它横跨太多学科,是个多层抽象的“兔子洞”。我擅长射频硬件和天线设计(以此为业);也涉猎过 DSP 和 FPGA,用 Verilog 拼过射频进 USB 出的模块;后来又学 GNU Radio 和 Python 写了个应用;接着又得面对 C++ 和整个 Linux 开发环境,还在消化中。

The hard part, and cool thing, about SDR is that it covers so many disciplines. It's the proverbial rabbit hole, with multiple layers of abstraction. I'm very good at RF hardware and antenna design; grok that as I do it for a living. I have dabbled in DSP and FPGAs, hacking some Verilog together with Xilinx blocks to do RF in to USB out. Not a DSP comms guru, but know my way around the theory. Then got into GNU Radio, so had to learn Python. Got the basics down on that and wrote a GNU radio based app, putting it on Github. Though then came C++, and the whole Linux development environment. Totally new stuff to delve into. Still trying to wrap my head around that.
畅想手机端 SDR 结合 DHT 实现终端间直接无线通信的未来。
真希望能在 Android 上玩基础 SDR。大家谈去中心化、隐私和网络中立,但手持设备上的 SDR 会非常令人兴奋——终端之间无线传输小段数据会打开许多新软件的大门。DHT 已是比特币的核心却少有人谈论,把 DHT 概念搬到 SDR 上听起来是未被探索的方向,应该是未来互联网的样子。

I really wish that I could do some basic sdr with android. People talk about decentralization and privacy and net neutrality, but sdr on handheld would sound very exciting. I'm sure ISPs would argue against it, but communicating small segments of data wirelessly between terminals would open a lot of gates for new kinds of software. Dht is already at the core of Bitcoin, yet it's not talked a lot about. Dht, to me, is the most important networked algorithm. Implementing the concepts of dht over sdr sounds new and unexplored, but it should be the internet of the future...
分享 AirplaneJS 这个用 Node.js 接收飞机 ADS-B 信号的 SDR 应用实例。
昨天刚发现 AirplaneJS:它能接收飞机的 ADS-B 无线电信号,在浏览器地图上显示,像本地版的 Flightradar。很高兴能在 Node.js 里玩 SDR。这本书第 13 章还有更高级的 SDR 应用。大家还知道哪些有趣或高级的 SDR 应用?

Not really related to the book, but it's only yesterday that I've found out about AirplaneJS [0]. It picks up ADS-B radio signals from airplanes and display them over maps on browser like a local Flightradar. It's nice that you can interact with SDR in Node.js About this book, it's interesting to see that there are more advanced applications of SDR on Chapter 13. Do you, HN-friends, know any other toy/simple or advanced applications of SDR? [0] https://github.com/watson/airplanejs
