The choice of radio waveform is the core physical-layer decision for any wireless access technology. After assessments of all the waveform proposals, 3GPP adopted OFDM with a cyclic-prefix for both DL and UL transmissions, currently implemented in the library. Like all of the communications standards incorporated within AWR VSS software, the library provides specification of the channel coding, multi- plexing, and mapping to physical channels for 5G NR. Testbenches The library offers pre-configured testbenches for the latest 5G signals and frameworks proposed by various industry groups. With AWR VSS software, systems engineers can optimize the performance of RF front-end components, such as power amplifiers, based upon PAR, ACLR, EVM, or any number of performance metrics. The software enables designers to evaluate the in-situ performance of other devices in the system, not just for 5G FR1 and FR2, but also for all current cellular standards. EVM measurements can be made on individual sub-carriers and/ or over the OFDM symbol. Adjacent channel interference analysis can also be easily performed. AWR VSS users can insert their 5G component or subsystem designs into the testbenches and evaluate their performance under 5G systems requirements. Phased Arrays The library provides a framework supporting phases of phased array design configuration, analysis, and optimi- zation. Antenna radiation data from simulation/measured data can be imported into the phase array generator wizard, allowing designers to use the same antenna response as they optimize the array configuration and develop the feed network. The wizard generates the entire phased array component in a hierarchical network that includes the feed structure (combiner/divider), amplitude/phase control per radiating element, and the antenna array itself—ready for EM analysis.
