Asymptotic Capacity Gain of Transmit Antenna Selection
Antenna selection provides a low-cost low complexity solution for MIMO systems, in particular transmit antenna selection exploits partial knowledge of the channel that can be made available without excessive feedback bandwidth. In this work we explore information theoretic limits of transmit antenna selection for high SNR and large number of transmit antennas. We define the capacity gain as the...
متن کاملgenetic variation and genetic gain from selection in bread wheat
genetic variation is necessary factor for continued breeding and increasing genetic gain from selection in crop plants. to evaluate genetic variation and genetic gain from selection in bread wheat, 45 genotypes consisting of 9 cultivars and their 36 crosses were grown in a randomized complete block design with three replications in research farm of isfahan university of technology. the phenotyp...
متن کاملSignal Correlations and Diversity Gain of Two-Beam Microcell Antenna
The motivation of the present study is to investigate the possibility of using two independently directed antenna beams in a mobile base station to provide diversity gain and reduce fading problems in a microcellular environment. In this paper, the signal correlation of the individual antenna beams is studied, and it is shown that correlation depends on beamwidth, separation angle of the antenn...
متن کاملMaximum-Gain Working Set Selection for SVMs
Support vector machines are trained by solving constrained quadratic optimization problems. This is usually done with an iterative decomposition algorithm operating on a small working set of variables in every iteration. The training time strongly depends on the selection of these variables. We propose the maximum-gain working set selection algorithm for large scale quadratic programming. It is...
متن کاملFeature Selection based on Information Gain
The attribute reduction is one of the key processes for knowledge acquisition. Some data set is multidimensional and larger in size. If that data set is used for classification it may end with wrong results and it may also occupy more resources especially in terms of time. Most of the features present are redundant and inconsistent and affect the classification. In order to improve the efficien...
