MathWorks DC Wireless Day

Please join us at our MathWorks Chevy Chase office on November 4^th for a two-part wireless day.Learn more about the topics below:

SatCom with MATLAB – 10-11am 

This seminar will show how to model multi-domain scenarios that include satellites, aircraft, ground stations, and moving ground vehicles.  Learn how to model and visualize asset trajectories and perform visual access calculations and link budget analyses.  The session will also address link budget analysis for RF and optical links.  The seminar will also show how to perform end-to-end link simulations with standards-based signals like 5G NTN, DVB-S2/S2X/RCS2, and GPS.  Explore the physical layer algorithms together with RF components and ground station receivers.  

Highlights

• Visualize 2D and 3D satellite orbits, fields of view, and ground tracks.
• Analyze line-of-sight access and compute link closures in integrated scenarios that include satellites, ground stations and aircraft.  Extend the technique to incorporate moving ground vehicles.
• Demodulate and decode 5G NTN signals that have been impaired by 3GPP-specified NTN channel models.
• Demodulate DVB-S2 signals that are subject to severe Doppler shifts, sample clock offset, and phase noise.
• Demodulate a composite waveform from multiple GPS satellites.  Perform acquisition, tracking, and bit processing on a signal impaired with Doppler and thermal noise.  Decode the bits to determine the location of a GPS receiver.

Antenna to Bits – 11am-12pm

This seminar presents a comprehensive walkthrough of RF front-end design using MATLAB and Simulink, showcasing the full signal path from antenna to digital bits. Attendees will see the design process of modeling a MIMO transmitter system, beginning with RF budget analysis and progressing through antenna and array design, beamforming, and PCB power divider integration. The session demonstrates how to build and simulate RF chains both interactively and programmatically, analyze antenna performance, and implement beamsteering using phased arrays. Each design stage is supported by system-level simulations that incorporate real-world effects such as impedance mismatches, coupling, and nonlinearities. 

The webinar culminates in a 5G signal simulation using a standard-compliant 3GPP waveform, integrating the RF system into a MATLAB testbench to measure key performance metrics like EVM and PAPR. Participants will gain insights into how MATLAB tools streamline the design and verification of complex RF systems, from initial concept to final validation. This session is ideal for engineers and researchers working in wireless communications, offering practical techniques for modeling, simulation, and performance evaluation of next-generation RF systems. 

SatCom Workshop 1-3pm

In this hands-on tutorial, you will walk through a series of online satellite communications exercises.  These guided exercises will give you the opportunity to write and run your own MATLAB code for these exercises, and learn how, with minimal coding, you can streamline your satellite-related workflows.  The hands-on exercises will cover the following workflows:

• Set up and launch a satellite scenario viewer
• Compute and visualize the visibility access between a satellite and a ground station

Explore NTN coverage over a large region of Earth using several satellite constellations
