Motivation: to investigate a pilot signal that emulates acquisition bandwidth for reliable frequency offset tracking and corrections of an asynchronous receiver.
Goal(s): to achieve successful on-coil digitizer operation over a wireless MRI data link.
Approach: by creating synchronous and asynchronous time series using two software-defined radios with pre-defined chirp pulse train and characterizing and correcting distortions on images.
Results: Chirp pulse train can emulate image acquisition bandwidth and correct offsets, exhibiting non-coherent residual artifacts when unmixing.
Impact: Pilot chirp can improve the usability of tracking and correcting offset distortions associated with asynchronous free-running receivers.
