Wireless Communications Systems Design with MATLAB and USRP Software-Defined Radios

This two-day course shows how to design and simulate single- and multi-carrier digital communications systems using MATLAB^®. Multi-antenna and turbo-coded communication systems are introduced, and different channel impairments and their modeling are demonstrated. Components from LTE and IEEE 802.11 systems will be used as examples. The instructor will demonstrate a radio-in-the-loop system using real-time hardware (RTL-SDR and USRP^®).

The target audience for this course includes system engineers and RF engineers who need a fast ramp-up on modern communication techniques and the radio-in-the-loop workflow.
