5G NR Downlink OFDM Waveform Explained with MATLAB simulation

🔍 In this video, we introduce the structure of the 5G NR downlink waveform, covering key concepts such as OFDM symbols, slots, subcarriers, resource elements, and resource blocks. We also explain how numerology and bandwidth parts shape the waveform and enable flexible spectrum use.

Then, we switch to MATLAB and demonstrate how to generate a 5G downlink signal using the 5G Toolbox. You'll learn how to visualize the waveform, identify key physical channels like SSB and PDCCH, and configure waveform generation for different scenarios.

🧠 What you’ll learn:
✅ Basics of the 5G time-frequency grid
✅ Role of subcarriers, slots, and resource blocks
✅ How 5G numerology works
✅ Introduction to physical channels: PBCH, PDCCH, PDSCH
✅ How to simulate 5G downlink waveforms in MATLAB
