mmWave Massive MIMO with Simple RF and Appropriate DSP
Amine Mezghani, A. Lee Swindlehurst
There is considerable interest in the combined use of millimeter-wave (mmwave) frequencies and arrays of massive numbers of antennas (massive MIMO) for next-generation wireless com…
Low SNR Asymptotic Rates of Vector Channels with One-Bit Outputs
Amine Mezghani, Josef A. Nossek, A. Lee Swindelhurst
We analyze the performance of multiple-input multiple-output (MIMO) links with one-bit output quantization in terms of achievable rates and characterize their performance loss comp…
Hybrid Precoder and Combiner Design with Low Resolution Phase Shifters in mmWave MIMO Systems
Zihuan Wang, Ming Li, Qian Liu +1
Millimeter wave (mmWave) communications have been considered as a key technology for next generation cellular systems and Wi-Fi networks because of its advances in providing orders…
A Comparison of Hybrid Beamforming and Digital Beamforming with Low-Resolution ADCs for Multiple Users and Imperfect CSI
Kilian Roth, Hessam Pirzadeh, A. Lee Swindlehurst +1
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…
Blind Estimation of Sparse Broadband Massive MIMO Channels with Ideal and One-bit ADCs
Amine Mezghani, A. Lee Swindlehurst
We study the maximum likelihood problem for the blind estimation of massive mmWave MIMO channels while taking into account their underlying sparse structure, the temporal shifts ac…
Massive MIMO Downlink 1-Bit Precoding with Linear Programming for PSK Signaling
Hela Jedda, Amine Mezghani, Josef A. Nossek +1
Quantized massive multiple-input-multiple-output (MIMO) systems are gaining more interest due to their power efficiency. We present a new precoding technique to mitigate the multi-…
