Deep Weighted MMSE Downlink Beamforming
ICASSP 2021 - 2021 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2021The weighted minimum mean square error (WMMSE) algorithm was proposed to provide a locally optimum solution to the otherwise NP-hard weighted sum rate maximization beamforming problem, but it can still be prohibitively complex for real-time implementation. With the success of deep unfolding in trading off complexity and performance, we propose to apply

2012 10th International Symposium on Electronics and Telecommunications, 2012
This paper investigates the effect of SINR in LTE downlink transmission. 3GPP Long Term Evolution (LTE) is the evolution of the Universal Mobile Telecommunications System (UMTS) which will make possible to deliver next generation high quality multimedia services according to the users' expectations. The results of this simulation serves to evaluate the

WCDMA downlink capacity - part 1
14th IEEE Proceedings on Personal, Indoor and Mobile Radio Communications, 2003. PIMRC 2003., 2004In this paper we propose a semi-analytical approach, to evaluate WCDMA downlink capacity. New results are provided, with respect to literature, related to the role of the soft handover process and SSDT Mode (site selection diversity transmission power control) in network dimensioning. Moreover, the impact of sectorization has been taken into account in

Uplink to downlink spatial covariance matrix transformation concepts for downlink beamforming
Proceedings of the 3rd IEEE International Symposium on Signal Processing and Information Technology (IEEE Cat. No.03EX795), 2004We present a comparison of several uplink to downlink covariance matrix transformation methods that can be used in downlink beamforming for frequency selective channels of frequency division duplex (FDD) systems. The performance improvement obtained from the transformation methods is compared with that from the method, which directly uses the uplink ...

Robust uplink to downlink spatial covariance matrix transformation for downlink beamforming
2004 IEEE International Conference on Communications (IEEE Cat. No.04CH37577), 2004We propose a new uplink to downlink spatial covariance matrix transformation technique that provides robustness against uplink steering vector mismatches for frequency duplex systems (FDD) in a frequency selective fading environment. Our approach leads to a matrix robust least squares (RLS) problem that can be formulated in a convex form as a second ...

The Gaia survey mission, operated by the European Space Agency (ESA) and launched on 19 December 2013, will survey approximately 109 stars or 1% of the galactic stellar population over a 5.5 year period. The main purpose of this mission is micro-arcsecond astrometry, that would yield important insights into the kinematics of the galaxy, its evolution ...
