Communications/Radar Systems

Cadence® AWR® Visual System Simulator™ (VSS) RF/wireless communications and radar system design software provides link budget and spurious heritage analysis, along with end-to-end time-domain and circuit-envelope simulations. With AWR VSS software, wireless design teams apply behavioral, impedance-aware RF models and baseband signal processing blocks to develop and optimize system architectures and determine component specifications for best overall performance. Users can simulate system metrics such as adjacent channel power ratio (ACPR), bit-error rate (BER), and error vector magnitude (EVM) with pre-configured and user-defined virtual testbenches, as well as identify the source of spurious products and other system impairments.

The AWR VSS Advantage

Fast

Impedance-aware behavioral modeling for rapid architectural design, budget and spur analysis, and component specification

Smart

Circuit and electromagnetic (EM) co-simulation to incorporate accurate component-level design into RF-to-baseband communications system development

Validate

Virtual testbenches provide pre-configured modulated signal sources and measurements for popular wireless communication standards
