5G radio, improves spectral efficiency while offering unrivaled network capacity. 5G New Radio technology is based on adaptable OFDM waveforms and multiple access techniques that have been optimized ...

These experiments used a 160 GHz carrier frequency and a 5G-NR compliant OFDM waveform, highlighting dual-user operations and dual-beam capabilities to overcome environmental blockage challenges.

On the other hand, as shown in Chapters 3 and 4, to maintain orthogonality among subcarriers even in multipath fading channels, each OFDM symbol is cyclically extended with a guard interval, whose ...
