MAGNETAR is presented, which infers a joint posterior over planar transmitter position and heading from a single asynchronous radio-frequency multipath snapshot, represented by angle-of-arrival and signal-to-noise-ratio estimates, given the room layout and receiver pose.

By intelligently nulling interference *before* matrix inversion, massive MIMO systems can achieve near-optimal beamforming with significantly reduced computational complexity, even in finite-precision hardware.
