Nonlinear 1-Bit Precoding for Massive MU-MIMO with Higher-Order Modulation
Sven Jacobsson, Giuseppe Durisi, Mikael Coldrey +2
Massive multi-user (MU) multiple-input multiple- output (MIMO) is widely believed to be a core technology for the upcoming fifth-generation (5G) wireless communication standards. T…
Quantized Precoding for Massive MU-MIMO
Sven Jacobsson, Giuseppe Durisi, Mikael Coldrey +2
Massive multiuser (MU) multiple-input multiple-output (MIMO) is foreseen to be one of the key technologies in fifth-generation wireless communication systems. In this paper, we inv…
PhaseMax: Convex Phase Retrieval via Basis Pursuit
Tom Goldstein, Christoph Studer
We consider the recovery of a (real- or complex-valued) signal from magnitude-only measurements, known as phase retrieval. We formulate phase retrieval as a convex optimization pro…
Data Detection in Large Multi-Antenna Wireless Systems via Approximate Semidefinite Relaxation
Oscar Castañeda, Tom Goldstein, Christoph Studer
Practical data detectors for future wireless systems with hundreds of antennas at the base station must achieve high throughput and low error rate at low complexity. Since the comp…
