Downlink MIMO in LTE-advanced: SU-MIMO vs. MU-MIMO
IEEE Communications Magazine, 2012Single-user multi-antenna technologies are well upported in current standard specifications like LTE Release 8/9. Further development of the specification (LTE-Advanced) is expected to conform to the requirements for IMT-Advanced systems. One of the key enabling features of LTE-Advanced to meet IMT-Advanced downlink performance requirements is multi ...

2012 IEEE First AESS European Conference on Satellite Telecommunications (ESTEL), 2012
The presence of fading in radio communications is the major impairment to reach the promised capacity. Diversity is a way to limit the fading effects and MIMO is a technique to exploit it. It is shown that in terrestrial mobile radio communications MIMO is an effective techniques while for satellite systems it requires further study to exploit possible

According to previsions, Spanish population over 65 years old will soon be an important fraction. For the EU region, old-age dependency ratios will more than double in 2000 to 2050, decreasing, at the same time, the ratio of persons of working age to every elderly people. These data show the need for some helping technologies that make possible to deal

Full dimension mimo (FD-MIMO): the next evolution of MIMO in LTE systems
IEEE Wireless Communications, 2014Full dimension MIMO has attracted significant attention in the wireless industry and academia in the past few years as a candidate technology for the next generation evolution toward beyond fourth generation and fifth generation cellular systems. FD-MIMO utilizes a large number of antennas placed in a 2D antenna array panel for realizing spatially ...

5G Enabling Technologies - MIMO, Multiuser MIMO, and Massive MIMO Slides
2017In this webinar, the fundamentals underlying the MIMO concept are explained. It will be shown how multiple reflections in indoor and urban environments can be effectively used to create additional independent channels that can serve the purposes of diversity and/or spatial multiplexing.

Broadband MIMO antennas for MIMO radar systems
2013 IEEE Antennas and Propagation Society International Symposium (APSURSI), 2013Methods of reducing both electric and magnetic field coupling for enhancing the isolation in broadband MIMO antenna system is presented. The proposed MIMO antenna consists of two coplanar waveguide (CPW) fed self-complementary antennas (SCAs) and a U-shaped slot is etched on the ground plane.

BER-Allocation in MIMO and MIMO-OFDM
2006 IEEE International Symposium on Information Theory, 2006Adaptive bit loading algorithms are proposed for MIMO and MIMO-OFDM systems, thus better exploiting space and frequency diversity. Constant power allocation is assumed over all subchannels while the bit error rate is unconstrained. An efficient bit loading algorithm, which maximizes system bit rate under target mean BER restriction is formulated for a ...

Overlapped-MIMO Radar and MIMO Cellular System
2017In this chapter, we explore a collocated overlapped multiple-input multiple-output (Overlapped-MIMO) radar waveform design, which is combined with an algorithm to share spectrum through null space projection (NSP) for the coexistence of radar and communications system.
