An ESPRIT-Based Approach for 2-D Localization of Incoherently Distributed Sources in Massive MIMO Systems

Abstract

Abstract-In this paper, an approach of estimating signal parameters via rotational invariance technique (ESPRIT) is

5G Position and Orientation Estimation through Millimeter Wave MIMO

“…The use of 5G technologies to obtain position and orientation was previously explored in [7]- [9] for mm-wave and in [10]- [12] for massive MIMO. The early work [7] considered estimation and tracking of DOA through beam-switching.…”

“…A different approach was taken in [9], where meter-level positioning accuracy was obtained by measuring received signal strength levels. In the massive MIMO case, [10] considered estimation of angles, while [11] treated joint estimation of delay, AOD, and AOA, and evaluated the impact of errors in delays and phase shifters. However, no formal treatment regarding sufficient conditions for well-posed position and orientation estimation with one base station (BS) were provided.…”

Large-scale MIMO is capable of eliminating power-thirsty channel coding for wireless transmission of HEVC/H.265 video

“…Hence, in the uplink LS-MIMO system considered, N t was set to N t = {2, 4, 6}, and N r was set to the moderate value of 40, while in most of the LS-MIMO literature [9][10][11][12] hundreds of BS antennas are typically assumed. As a result, the uplink transmit power of each user in our LS-MI-MO system becomes 1/2, 1/4, and 1/6 of the total transmit power, respectively.…”

“…In the second direction, as one of the key technologies for future fifth generation (5G) wireless communications, large-scale multiple-input multiple-output (LS-MIMO) techniques have been shown to be capable of providing substantial transmission rate, reliability, and/or energy efficiency improvements through the use of a large number of base station (BS) antennas [9][10][11][12].…”

A beamspace approach for 2-D localization of incoherently distributed sources in massive MIMO systems

“…Additionally, the approximations for deriving the linear relation in this approach are in fact unnecessary. The ESPRIT approach has also been extended to estimate both the 2-D nominal DOAs and the angular spreads of ID sources in massive MIMO systems, imposing a low computational complexity [39], but this approach can only be employed with URAs. Furthermore, in contrast to the above-mentioned methods that are all based on the antenna-element space, the beamspace based approach was shown to be capable of achieving low computational complexity [40], hence it has been employed to improve the conventional element-spaced based ESPRIT in [41,42].…”
