The basic concept of diversity; where two or more inputs at the receiver are used to get uncorrelated signals. aim this paper is an attempt compare some possible combinations diversity reception and MLSE detection techniques. Various combining techniques can be distinguished: Equal Gain Combining (EGC), Maximal Ratio (MRC), Selection Switching (SS).The simulation results shows that MRC give bet...

the crown wart disease caused by urophelyctis leproides on sugar beet is very important in the growing areas of north khuzestan influencing quantity and quality of the crop. the objectives of our research were to estimate general combining ability (gca) and specific combining ability (sca) of sugar beet lines as well as the gene action governing resistance to this disease. a randomized complete...

This paper addresses the antenna subset selection in multiple antenna systems with full diversity transmission, for both correlated and uncorrelated channels. To reduce the severe performance degradation of traditional selection/combining schemes, we prpose to embed phase-shift-only operations in the RF chains before selection. The resulting system shows a significant advantage in utilizing the...

WiMAX (Worldwide Interoperability for Microwave Access) is a promising technology which can offer high speed voice, video and data services upto the requirements at the customer’s end. The objectives of this paper is to evaluate the Performance evaluation of a WiMAX system under various diversity schemes (Selection combining, Maximal ratio combining and Equal gain combining), employing differen...

In this paper, we consider an amplify-and-forward cooperative wireless network in which network nodes use multiple input multiple output (MIMO) spatial division multiplexing (SDM) to communicate with one another. We examine the problem of distributed cooperative relay selection and signal combining at the destination. First, we propose three distributed relay selection algorithms based on the m...

Using an ensemble of classi ers, instead of a single classi er, can lead to improved generalization. The gains obtained by combining however, are often a ected more by the selection of what is presented to the combiner, than by the actual combining method that is chosen. In this paper we focus on data selection and classi er training methods, in order to \prepare" classi ers for combining. We r...

Performance analysis of switched-and-stay combining (SSC) and selection combining (SC) diversity receivers operating over correlated Nakagami-m fading channels in the presence correlated Nakagami-m distributed co-channel interference (CCI) is presented. Novel infinite series expressions are derived for the output signal to interference ratio's (SIR’s) probability density function (PDF) and cumu...
