Exploiting Geometry in the SINR$$_k$$ Model
2015We introduce the SINR\(_k\) model, which is a practical version of the SINR model. In the SINR\(_k\) model, in order to determine whether \(s\)’s signal is received at \(c\), where \(s\) is a sender and \(c\) is a receiver, one only considers the \(k\) most significant senders w.r.t. to \(c\) (other than \(s\)).

NDA estimation of SINR for QAM signals
IEEE Communications Letters, 2005Estimation of signal-to-interference-plus-noise ratio in a system using quadrature amplitude modulation is studied. Non-data-aided moment-based estimators are derived for a slowly fading channel under two conditions. The biases and the root mean square errors of the estimators are examined.

On the Distribution of SINR for MMSE MIMO Systems
IEEE Transactions on Communications, 2019While the performance analysis of linear zero-forcing (ZF) and minimum mean-square error (MMSE) receivers has received much attention, there has been no exact closed-form distribution of signal-to-interference-plus-noise ratio (SINR) for MMSE multiple-input multiple-output (MIMO) systems in the arbitrary fading environments for over the past 20 years ...

Broadcast in the Ad Hoc SINR Model
2013An increasing amount of attention is being turned toward the study of distributed algorithms in wireless network models based on calculations of the signal to noise and interference ratio SINR. In this paper we introduce the ad hoc SINR model, which, we argue, reduces the gap between theory results and real world deployment.

SINR Maps: Properties and Applications
2011Most algorithmic studies in wireless networking to date employ simplified graphbased models such as the unit disk graph (UDG) model. These models conveniently abstract away complications stemming from interference and attenuation, and thus make it easier to deal with algorithmic issues.

Interference and SINR in Dense Terahertz Networks
2015 IEEE 82nd Vehicular Technology Conference (VTC2015-Fall), 2015Over the last decade short-range communications in the terahertz band have been extensively studied as a technology-enabler for dense and ultra-dense wireless networks. Recent advances in miniaturized terahertz transceivers design promise wireless connectivity and simultaneous interaction between thousands of devices.

Fully Dynamic Broadcasting under SINR
2018 IEEE 37th International Performance Computing and Communications Conference (IPCCC), 2018Dynamicity is one of the critical characteristics and a major challenge in designing communication protocols in wireless networks. Most of the previous works had focused on the internal node changes (e.g., mobility, arrival, or departure) and not considered the effect of external environmental change.

An Eavesdropping Game with SINR as an Objective Function
2009We examine eavesdropping over wireless channels, where secret communication in the presence of an eavesdropper is formulated as a zero-sum game. In our problem, the legitimate receiver does not have complete knowledge about the environment, i.e. does not know the exact values of the channels gains, but instead knows just their distribution.

BROADCAST SCHEDULING PROBLEM IN SINR MODEL
International Journal of Foundations of Computer Science, 2014Our work is to study the Minimum Latency Broadcast Scheduling problem in the geometric SINR model with power control. With power control, sensor nodes have the ability to adjust transmitting power. While existing works studied the problem assuming a uniform power assignment or allowing unlimited power levels, we investigate the problem with a more ...

2006 IEEE 17th International Symposium on Personal, Indoor and Mobile Radio Communications, 2006
In this paper we consider the Signal to Interference plus Noise Ratio (SINR) criterion for connectivity, as a basis for a wireless ad hoc network and present a detailed study for the power performance of such a network. For this, we examine how typical wireless network parameters such as, network density and environment variables such as the path loss ...
