AWR Visual System Simulator 2 www.cadence.com/go/awr Product Strengths Digitally Modulated Systems Design and simulate system architectures and components with IP libraries for wireless communication standards, including LTE-A, 5G, narrowband IoT, and more. Preconfigured testbenches support transmitter confor- mance testing and receiver sensitivity analysis, as well as circuit co-simulation, for linearity measurements such as adjacent channel power ratio (ACPR) and BER of power amplifiers (PAs) operating under high peak-to-average power ratio (PAPR). Link Budgets and Spur Analysis Perform RF-cascaded measurements such as gain, noise figure (NF), and third-order intercept (IP3) while accounting for impedance mismatch throughout the signal path. The AWR VSS RF Inspector (RFI) frequency-domain simulation tool that helps designers identify frequency content (harmonic and intermodulation tones arising from device nonlinearity) anywhere along an RF link. Phased Array Systems Simulate critical antenna performance in phased arrays with a reconfigurable model supporting thousands of radiating elements based on measured or simulated antenna data for the development of beamforming algorithms, evaluation of hardware impairments, and RF link analysis. The unique, open, and integrated environment of VSS enabled us to study the effects of the nonlinear distortion on our communications link margin using real digital modulated analog waveforms. Stephan VanFleteren, General Dynamics Hardware in the Loop Plug-and-play support for co-simulation with LabVIEW, MATLAB, and C++ expands modeling capabilities with custom models, automation scripts, and user-defined signal processing algorithms. Testbenches Testbenches are pre-configured for common measure- ments such as ACPR, error vector magnitude (EVM), spectral, and many other types of measurements. For instance, preconfigured testbenches with 5G NR signals and measurements support performance verification of components or subsystems with 5G NR standard test model signals. 5G/Radar Library (Option) The 5G/Radar library offers easy-to-configure signal sources and receivers that can be used for evaluation of RF components and/or RF links used in radar and 5G system- level measurements. Preconfigured measurements for 5G NR transmitter compo- nents include complementary cumulative distribution function (CCDF), AM to AM/PM, spectrum, EVM, ACPR, IQ constellation, and more. 5G NR receiver simulation sensi- tivity measurements include BER, block error rate (BLER), and throughput. For radar applications, the library offers radar signal gener- ation, radar-specific target and propagation modeling, and radar signal processing capabilities, including moving target indicator (MTI), moving target detector (MTD), and constant false-alarm rate calculator (CFAR).
