Position Information from Single-Bounce Reflections

Anastasios Kakkavas, Mario H. Castañeda García, Gonzalo Seco-Granados +3

In the context of positioning a target with a single-anchor, this contribution focuses on the Fisher information about the position, orientation and clock offset of the target prov…

Power Allocation and Parameter Estimation for Multipath-based 5G Positioning

Anastasios Kakkavas, Henk Wymeersch, Gonzalo Seco-Granados +3

We consider a single-anchor multiple-input multiple-output (MIMO) orthogonal frequency-division multiplexing (OFDM) system with imperfectly synchronized transmitter (Tx) and receiv…

Channel Parameter Estimation for Millimeter-Wave Cellular Systems with Hybrid Beamforming

Fazal-E-Asim, Felix Antreich, Charles C. Cavalcante +2

To achieve high data rates defined in 5G, the use of millimeter-waves and massive-MIMO are indispensable. To benefit from these technologies, an accurate estimation of the channel…

Massive MIMO Channel Estimation with Low-Resolution Spatial Sigma-Delta ADCs

Shilpa Rao, Gonzalo Seco-Granados, Hessam Pirzadeh +2

We consider channel estimation for an uplink massive multiple-input multiple-output (MIMO) system where the base station (BS) uses an array with low-resolution (1-2 bit) analog-to-…

On the Effect of Mutual Coupling in One-Bit Spatial Sigma-Delta Massive MIMO Systems

Hessam Pirzadeh, Gonzalo Seco-Granados, A. Lee Swindlehurst +1

The one-bit spatial Sigma-Delta concept has recently been proposed as an approach for achieving low distortion and low power consumption for massive multi-input multi-output system…

Limits of Transmit and Receive Array Gain in Massive MIMO

Tobias Laas, Josef A. Nossek, Wen Xu

In this paper, we consider the transmit and receive antenna array gain of massive MIMO systems. In particular, we look at their dependence on the number of antennas in the array, a…
