Recorded Webinar: Advanced Topics in Wireless System Design – Modeling RF Circuit Impairments

Wireless communication system engineers want to “speak a little RF” in order to bridge the gap between themselves – who prefer to think in terms of bit error rate and related characteristics such as Eb/No, delay spread, and intersymbol interference -- and their colleagues, the RF engineers -- who prefer to think in terms of network parameters, noise figure, and IP3.

Of course fundamentally the concepts are closely related -- RF impairments and their affect on system performance -- but how to get these two groups on the same page?

MathWorks customers have had great success in opening up this dialog using a method we call Model-Based Design: System engineers create an executable specification in the form of a Simulink® model that can be used to determine RF specifications. RF engineers use their third-party RF circuit transistor-level tools (e.g., harmonic balance) to build an RF circuit that meets the spec. Once they have a candidate solution, they can extract a verification model and give it back to the system engineers. They import this into the Simulink model and verify the overall performance of the system with the impairments from the candidate RF circuit included.

The two engineering teams can go back and forth, iterating to find an optimal solution as the design effort proceeds. Perhaps the RF section can use a more efficient or less costly circuit if the signal processing algorithms are improved a bit.  Or perhaps a small increase in fixed-point word length can free up some of the implementation loss budget to enable a lower cost or lower current RF component to be used. These opportunities for design optimization are enabled by allowing the two groups of engineers to speak the other’s language.

This webinar shows you how to get the conversation going.
