DVB-S2X Modem Prototype
With the increase in additional surveillance capabilities, and battle-fronts to monitor and defend, Command, Control, Communications, Computers, Intelligence, Surveillance and Reconnaissance (C4ISR) has become proportionally more dependent on SATellite COMmunication (SATCOM). Consequently, commercial SATCOM provides 80% of the Department of Defense (DoD)'s total capacity [1]. To this end, High Throughput Satellite (HTS) SATCOM has become a key interest.

Decoding a Car Key Fob with the USRP B206mini and GNU Radio
Modern car key fobs are simple on the outside and surprisingly sophisticated on the air. In this article, I walk through a practical, end-to-end workflow to capture and inspect a key fob’s RF frame using the new USRP B206mini-i, from raw I/Q samples to a clean binary sequence you can analyze.
Flexible Channel Emulation Workflows on USRPs with MATLAB® and Simulink®
This application note describes a MATLAB® and Simulink® model-based design workflow for developing, deploying, and validating wireless signal processing functions on the FPGA of NI USRP radios using Wireless Testbench™. The note uses SISO terrestrial channel emulation as a representative example. In this workflow, MATLAB is used for scenario definition, waveform and test vector generation, reference modeling, device control, and result analysis, while Simulink is used to architect an HDL-compatible implementation for deployment to the radio FPGA and iterate over fixed-point data conversion. The example demonstrates how a channel emulation design can move from a behavioral model to hardware validation while remaining extensible to broader use cases, such as MIMO, NTN, AI training data generation, and low-PHY exploration in O-RAN systems.
