Practical Signal Decomposition via Software Defined Radio
summary
Software-defined radio is shown as a practical toolset: RTL‑SDR ≈ $20 for 433/868/915 MHz captures, USRP and Bottlenose for live spectrograms, and GNU Radio + GR‑LoRa for decoding. A clear five-step physical‑layer workflow is given—channel, modulation, symbol rate, sync, decode—and IQ captures are saved and replayed later. Demonstrations include an RTL hierarchy in VHDL for prototyping, a live LoRa decode (including a satellite capture), and anecdotes of AIS spoofing and the Salamandra bug‑locating use.
