SINR Balancing with Coordinated Multi-Cell Transmission
2009 IEEE Wireless Communications and Networking Conference, 2009Coordinated multi-cell processing facilitates multi-user precoding techniques across distributed base station (BS) antenna heads. Hence, it can efficiently exploit the available spatial degrees of freedom in a multi-user multiple-input multiple-output (MIMO) channel.

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 ...

Downlink SINR distribution in a heterogeneous cellular wireless network with max-SINR connectivity
2011 49th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2011Recent results [1], [2] on the distribution of the downlink SINR in heterogeneous wireless networks assume that the serving base station (BS) for a given user (UE) location is either (a) the BS that is geographically nearest to the UE location [1], or (b) the one that has the highest received power at the UE location [2].

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.

Interference-aware SINR-based routing
ACM SIGMETRICS Performance Evaluation Review, 2007We consider the problem of mitigating interference and improving network capacity in, single-radio, single-channel, wireless multi-hop network. An ongoing aim of our research is to design a routing metric which is cognizant of interference. Modelling routing with a complete set of interference constraints is a NP-hard problem.

Maximum SINR beamforming for correlated sources
1995 International Conference on Acoustics, Speech, and Signal Processing, 2002We consider the signal-to-interference plus noise ratio (SINR) performance of several beamforming algorithms, taking particular account of the contribution of sources correlated with the desired signal. In addition, we derive an optimal method that maximizes SINR by combining with the desired signal estimate any components of the interference ...

SINR analysis in persymmetric adaptive processing
2016 IEEE Statistical Signal Processing Workshop (SSP), 2016We study the normalized output signal-to-interference-plus-noise ratio (SINR) of a sample matrix inversion (SMI) beamformer with exploiting a priori information on persymmetric structures in the received signal. An exact expression for the expectation of the normalized output SINR (i.e., average S-INR loss) of the persymmetric SMI beamformer is ...

Multicarrier equalization by subchannel SINR maximization
The Second International Conference on Communications and Networking, 20101 In multicarrier (MC) communication receivers, the use of a time-domain equalizer (TEQ) mitigates inter-symbol and inter-carrier interferences by shortening the overall channel delay spread. Nevertheless, the TEQ-based MC-receiver structure does not result in optimal bit rate and if one wants to optimize the bit rate a nonlinear cost function has to ...

Prefiltered Turbo Equalization With SINR Mismatch
2007 4th International Symposium on Wireless Communication Systems, 2007In this paper, we consider the use of a channel shortening prefilter in conjunction with a turbo equalizer, in order to allow its use with arbitrarily long channel impulse responses. We show that the residual intersymbol interference (ISI), caused by imperfect channel shortening, results in considerable performance loss.

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 ...
