Optimized Precoding for MU-MIMO With Fronthaul Quantization
Yasaman Khorsandmanesh, Emil Björnson, Joakim Jaldén
One of the first widespread uses of multi-user multiple-input multiple-output (MU-MIMO) is in 5G networks, where each base station has an advanced antenna system (AAS) that is conn…
Convex Quantization Preserves Logconcavity
Pol del Aguila Pla, Aleix Boquet-Pujadas, Joakim Jaldén
A logconcave likelihood is as important to proper statistical inference as a convex cost function is important to variational optimization. Quantization is often disregarded when w…
A matrix-inverse-free implementation of the MU-MIMO WMMSE beamforming algorithm
Lissy Pellaco, Joakim Jaldén
The WMMSE beamforming algorithm is a popular approach to address the NP-hard weighted sum rate (WSR) maximization beamforming problem. Although it efficiently finds a local optimum…
Inertial Navigation Using an Inertial Sensor Array
Håkan Carlsson, Isaac Skog, Gustaf Hendeby +1
We present a comprehensive framework for fusing measurements from multiple and generally placed accelerometers and gyroscopes to perform inertial navigation. Using the angular acce…
