Massive device connectivity with massive MIMO
2017 IEEE International Symposium on Information Theory (ISIT), 2017This paper studies a single-cell uplink massive device communication scenario in which a large number of single-antenna devices are connected to the base station (BS), but user traffic is sporadic so that at a given coherence interval, only a subset of users are active. For such a system, active user detection and channel estimation are key issues.

Demand for wireless throughput, both mobile and fixed, will always increase. One can anticipate that, in five or ten years, millions of augmented reality users in a large city will want to transmit and receive 3D personal high-definition video more or less continuously, say 100 megabits per second per user in each direction.

Massive MIMO With Ternary ADCs
IEEE Signal Processing Letters, 2020Massive multiple-input-multiple-output (MIMO) system inevitably faces the hardware cost and energy efficiency problem due to its large number of antennas at the base station (BS). The use of low-resolution analog-to-digital converters (ADCs), e.g., typical 1-bit ADCs, can effectively reduce the system cost.

Jamming Massive MIMO using Massive MIMO: Asymptotic separability results
2017 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2017Consider the uplink transmission of a single-cell multi-user multiple-input multiple-output (MIMO) system with K single-antenna users and a base station (BS) equipped with a very large number of antennas denoted by M. Consider a jamming device with N > M distributed antennas attempting to deteriorate the communication between the users and the BS.

Distributed Massive MIMO Downlink
ICC 2019 - 2019 IEEE International Conference on Communications (ICC), 2019The feasibility of adopting distributed massive multiple-input multiple-output (D-MMIMO) for mitigating the achievable rate loss incurred by spatially-correlated fading at space-constrained user antenna arrays when served by co-located massive MIMO (C-MMIMO) counterpart is investigated.

Quantized beamforming in Massive MIMO
2015 49th Annual Conference on Information Sciences and Systems (CISS), 2015We investigate the effects of quantized beamforming on the capacity of a Massive MIMO by deriving explicit performance formulas. Our approach is applicable to a large class of quantizations, including PSK, QAM and polar quantizations. We show that with any degree of quantization, the beamforming gain grows linearly with the number of transmit antennas.

We propose a new hardware architecture for cost-and size-effective implementation of massive MIMO transmitters based on load modulation that is fully compatible with standard receiver architectures. With load modulation, a massive MIMO transmitter can be driven by a single power amplifier operating at constant envelope.

IEEE Transactions on Vehicular Technology, 2016
In this paper, an emerging wireless communication concept, which is termed as spatial modulation (SM) for large-scale multiple-input–multiple-output (MIMO), is considered. The results show that from the information-theoretic perspective, SM achieves capacity comparable to the open-loop MIMO capacity, although a subset of transmit antennas is activated ...
