- Seminar: BLIND AND OFF-GRID ACOUSTIC ECHOES RETRIEVAL USING MULTICHANNEL ANNIHILATING FILTERS
Accurate characterization of microwave components operating in a 5G context heavily draws on the capability to impose carefully crafted excitation signals on the DUT. Spectral purity and accuracy of the excitation is a key issue to empower simple yet accurate extraction of information about the device.
Unfortunately, RF AWG’s often have a limited resolution and suffer from some spectral distortion that complicates data processing significantly.
You will perform a measurement-based compensation of the linear dynamics of the generator to start with. Next, you will quantify the power spectrum of the nonlinear distortion and design a spectrum controller that reduces this distortion. Finally, you will apply the designed scheme to compensate an AWG operating at IF frequencies first, and at RF frequencies next.
