System designers and R&D teams will include Digital, and RF expertise and will need to model in order to create algorithms, do end-to-end simulations and have a “golden” reference for verification so that they can fully design a functional and robust system. See Figure 2.
New enhancements have been added to the design phase, bringing more tools into the environment leading to end-to-end RF simulations done quickly.
Digital and RF co-design is made possible so that designers/R&D teams are able to look at such things as Digital Pre-Distortion (DPD) in a base station Power Amplifier (PA) using a designer’s unique DPD algorithm or a basic algorithm in MATLAB. Then monitoring the spectrum all the way through the signal chain with a simulated spectrum analyzer can be achieved.
This system works with key manufacturer’s components and demo boards/reference designs such as the Analog Devices AD9361 AGILE transceiver. See Figure 4.
