Statistical Properties and Variations of LOS MIMO Channels at Millimeter Wave Frequencies
Tim Hälsig, Darko Cvetkovski, Eckhard Grass +1
Measurement results for millimeter wave LOS MIMO systems are presented with a focus on time variation and multipath propagation. Different system setups are used, including 2x2 and…
Measurement Results for Millimeter Wave pure LOS MIMO Channels
Tim Hälsig, Darko Cvetkovski, Eckhard Grass +1
In this paper we present measurement results for pure line-of-sight MIMO links operating in the millimeter wave range. We show that the estimated condition numbers and capacities o…
Spatial Oversampling in LOS MIMO Systems with 1-Bit Quantization at the Receiver
Tim Hälsig, Berthold Lankl
In this paper we investigate the achievable rate of LOS MIMO systems that use 1-bit quantization and spatial oversampling at the receiver. We propose that by using additional anten…
Performance Evaluation of LOS MIMO Systems under the Influence of Phase Noise
Tim Hälsig, Berthold Lankl
To deal with the ever increasing data rate demand in wireless systems, suitable backhaul solutions have to be found. One option is to use LOS MIMO systems at mmWave frequencies, as…
Information Rates for Faster-Than-Nyquist Signaling with 1-Bit Quantization and Oversampling at the Receiver
Tim Hälsig, Lukas Landau, Gerhard Fettweis
Oversampling combined with low quantization resolutions has been shown to be a viable option when aiming for energy efficiency in multigigabit/s communications systems. This work c…
Channel Parameter Estimation for LOS MIMO Systems
Tim Hälsig, Berthold Lankl
In this paper we consider the estimation of channel coefficients and frequency offsets for LOS MIMO systems. We propose that by exploiting the structure of the channel matrix, whic…
