Max-min weighted downlink SINR with uplink SINR constraints for full-duplex MIMO systems

, 2017
In this paper, we investigate a max-min weighted signal-to-interference-plus-noise-ratio (SINR) problem in a full-duplex multiuser multiple-input-multiple-output system, where a full-duplex-capable base station (BS) equipped with multiple antennas ...

Exact SINR Statistics in the Presence of Heterogeneous Interferers [PDF]

, 2015
We derive new results for the higher-order moments of signal-to-interference-plus-noise ratio (SINR) in the presence of an arbitrary Poisson point process (PPP)-based heterogeneous interference field. The analysis leverages on a momentgenerating-function

Approximation Algorithms for Maximum Link Scheduling under SINR-Based Interference Model

International Journal of Distributed Sensor Networks, 2015
A fundamental problem in wireless networks is the maximum link scheduling (MLS) problem. In this problem, interference is a key issue and past researchers have shown that determining reception using Signal-to-Interference plus Noise Ratio (SINR) is more ...

Approximation Algorithms for Wireless Link Scheduling with SINR-based Interference [PDF]

, 2008
In this paper, we consider the classical problem of link scheduling in wireless networks under an accurate interference model, in which correct packet reception at a receiver node depends on the signal to interference plus noise ratio (SINR).

MVDR ALGORITHM BASED LINEAR ANTENNA ARRAY PERFORMANCE ASSESSMENT FOR ADAPTIVE BEAMFORMING APPLICATION [PDF]

Journal of Engineering Science and Technology, 2017
The performance of Minimum Variance Distortionless Response (MVDR) beamformer is sensitive to errors such as the steering vector errors, the finite snapshots, and unsatisfactory null-forming level. In this paper, a combination of MVDR with linear antenna
