Understand variables, data types, streams and vectors, runtime update mechanism
2. Intermediate and advanced applications
Custom Python modules, message passing, tags
Use DSP modules (low-pass filtering, frequency offset, rate conversion)
Realize modulation and demodulation (FM, SSB, QPSK, BPSK, OFDM, FSK)
3. Hardware combined with actual combat
RTL-SDR and USRP B200/B205 actual combat exercises
Design software spectrum analyzer, FM transceiver
Establish file transfer, packet communication system, etc.
4. Developer orientation
Create Out-Of-Tree module (Python/C++)
Use VOLK acceleration core
Link development with IDE (VS, Eclipse, Code::Blocks), remote control test
You can complete the basic module first, and then combine it with USRP Hardware practice, master the construction and optimization of SDR system step by step.
