Using Calibration to Optimize Performance in Crucial Measurements
Achieving the highest possible performance from circuits used in third-and fourth-generation wireless systems is driving a tighter integration of previously disparate tools. Certainly, a level of software synergy is essential when designing circuits for use in today’s wireless systems that employ higher-order modulation techniques together with advanced technologies, such as Orthogonal Frequency Division Multiplexing (OFDM), multiple-input multiple-output (MIMO) and digital predistortion (DPD) circuits, to name a few. As this white paper illustrates, AWR’s Visual System Simulator (VSS) and National Instruments’ LabVieW graphical programming environment are now co-simulating so as to better enable designers to analyze, optimize, and verify complex RF circuits, subsystems and digital signal processing within a unified framework. Before looking more closely into specific design scenarios, it is important to understand how this new and cohesive VSS/LabVIEW co-simulation environment works.
