16 QAM Communication with 1-Bit Transmitters
Donia Ben Amor, Hela Jedda, Josef A. Nossek
We present a novel non-linear precoding technique for the transmission of 16 quadrature amplitude modulation (QAM) symbols in a 1-bit massive multi-user (MU) multipleinput- single-…
Precoding under Instantaneous Per-Antenna Peak Power Constraint
Hela Jedda, Amine Mezghani, A. Lee Swindlehurst +1
We consider a multi-user (MU) multiple-input-single-output (MISO) downlink system with M single-antenna users and N transmit antennas with a nonlinear power amplifier (PA) at each…
Achievable Rate and Energy Efficiency of Hybrid and Digital Beamforming Receivers with Low Resolution ADC
Kilian Roth, Josef A. Nossek
For 5G it will be important to leverage the available millimeter wave spectrum. To achieve an approximately omni- directional coverage with a similar effective antenna aperture com…
Channel Estimation and Data Equalization in Frequency-Selective MIMO Systems with One-Bit Quantization
Javier García, Jawad Munir, Kilian Roth +1
This paper addresses channel estimation and data equalization on frequency-selective 1-bit quantized Multiple Input-Multiple Output (MIMO) systems. No joint processing or Channel S…
DOA Parameter Estimation with 1-bit Quantization - Bounds, Methods and the Exponential Replacement
Manuel Stein, Kurt Barbé, Josef A. Nossek
While 1-bit analog-to-digital conversion (ADC) allows to significantly reduce the analog complexity of wireless receive systems, using the exact likelihood function of the hard-lim…
Measurement-driven Quality Assessment of Nonlinear Systems by Exponential Replacement
Manuel Stein, Josef A. Nossek, Kurt Barbé
We discuss the problem how to determine the quality of a nonlinear system with respect to a measurement task. Due to amplification, filtering, quantization and internal noise sourc…
