The well-known distributed power control algorithm with temporary removal and feasibility check (DFC) improves outage probability but it is not able to improve and maximize the system throughput simultaneously. In this paper, we have proposed a new algorithm which gives an improvement in DFC algorithm such that it optimizes the transmission sum rate and reduces the number of outage users at the same...
MIMO downlink with base station coordination in a cellular network is considered. In centralized coordinated transmission from a cluster of base stations, the channel state information (CSI) of users needs to be sent to a central processor for precoding and resource allocation. Real time CSI feedback from the users to their home base station and from the base stations to the central processor is a...
The newborn's skull is composed of already ossified parts of the flat bone connected by areas of fibrous membrane not yet ossified, which are called fontanels. At birth, an infant has six of such fontanels. These two different tissue types forming the outer part of the neuro-cranium have different electrical conductivities. Thus, it is important to determine the exact geometry of the fontanels if...
This study presents an automatic model based technique for brain tissue segmentation from cerebral magnetic resonance (MR) images. In this paper, support vector machine (SVM) based classifier, as a new and powerful kind of supervised machine learning with high generalization characteristics, is employed. Here, least-square SVM (LS-SVM) in conjunction with brain probabilistic atlas as a priori information...
Iris segmentation, including localization and noise removal, is a fundamental step in iris recognition systems as the performance of the system is highly depend on this step. The aim of localization is to detect inner (pupil) and outer (limbic) boundaries. Noise removal consists of eliminating eyelids and eyelashes from localized image. In this paper, we propose a new localization algorithm, in which,...
This paper introduces a blind watermarking scheme based on remainder of distance vector between two wavelet blocks. In the proposed scheme, the wavelet coefficients from frequency sub-band LH3 and HL3 have been grouped into two blocks for invisible watermark embedding and extraction. In the next stage, the distance vectors between two blocks are computed and then remainder after division calculated...
