Very effective pattern recognition (PRT)
no vote
Application background An introduction into the setup, definitions and use of PRTools is given. PRTools4 is extended and enhanced with respect to version 3 and thereby not fully compatible with it. This manual includes the description of a further upgrade: PRTools4.1. Still not all possibilities are fully exploited on the user level, or not at all. See release notes on page 58. Readers are assumed to be familiar with Matlab and should have a basic understanding of field of statistical pattern recognition. Key Technology Pattern recognition  is a branch of  machine learning  that focuses on the recognition of patterns and regularities in data, alt

Analysis of DCT

Application background Diffraction Contrast Tomography has been used to map the three-dimensionalmicrostructure of a ceramic (coarse grain size polycrystalline alumina) for the first time. Thisnew synchrotron technique determines, non-destructively, the crystallographic orientation of each grain from its diffraction geometry. The 3D grain shapes are also obtained from projectedimages of the grains in the diffraction condition. Grain boundary structure can therefore becharacterised in terms of the physical grain boundary plane orientation and the crystalmisorientation of the adjacent grains. Key Technology Diffraction contrast tomography is a near-field diffraction-based imaging technique that provides high-resolution grain maps of polycrystalline materials simultaneously with the orientation and average elastic strain tensor components of the individual grai

Phased array antenna beam forming
no vote
Apply background beamforming and radiation patterns to various linear and planar phased array antennas, and present configurations. They are designed for wireless process monitoring using & nbsp; indoor position estimation & nbsp; applications based on radio signals arriving at & nbsp; (DOA) in a determined direction, arriving at & nbsp; (AOA) through measured angles. By applying antenna array elements between linear phase cones, a relatively simple design is provided. &Various antenna array configurations are studied, and an optimal indoor positioning and scanning system is obtained by numerical simulation. The key technology of beamforming & nbsp; & nbsp; spatial filtering & nbsp; is & nbsp; signal processing & nbsp; & nbsp; technology; sensor array & nbsp; directional signal transmission or reception. This is by combining elements with phased array in such a way that the signal experiences constructive interference at a specific angle and cancels and interferes with other people's experience. Beamforming can be used in both transmitter and receiver to achieve spatial selectivity. In contrast, the overall improvement of receive / transmit is called receive / transmit and transmit, gain and (or loss). Beamforming can be used for radio waves, or with sound waves. It has been found in many applications such as radar, sonar, earthquake, wireless communications, radio, astronomy, acoustics, and biomedicine. Adaptive beamforming is used to detect and estimate the signal of interest in the output of the signal, sensor array and, through optimal (e.g., least squares) spatial filtering and interference suppression

Frequency reuse scheme of LTE network
no vote
Application background: LTE advanced (LTE-A) is an evolved version of LTE, and the project name is developed by 3GPP. LTE-A will meet or exceed the requirements of the International Telecommunication Union (ITU) fourth generation (4G) wireless communication standard called IMT advanced. LTE advanced is part of the original version 10 of the 3GPP specification specified, with a feature freeze target of 2011. The LTE specification will continue in the subsequent 3GPP versions. This application note covers the following topics: · overview of 4G ITU requirements for LTE advanced An overview of 3GPP requirements, including the expected schedule of key solutions for LTE advanced release 10 and beyond: the technologies considered are expected to design and test challenges for key technologies in the face of increased traffic demand and interference limited cellular networks, fractional frequency reuse (FFR) is an attractive strategy due to its low complexity implementation with its significant bottom percentile mobility The revenue of users. Recently, FFR has included & nbsp; the fourth generation (4G) including WiMAX 2 wireless standard (802.16m) and 3gpp-lte & nbsp; since release 8. This work extends our new analytical model FFR in downlink & nbsp; cellular networks and single-layer base stations using PPP mode to develop & nbsp; access layers between general multi-layer networks and closed and open networks. This enables & nbsp; SINR distribution to be derived as a function of & nbsp; obedient expression development; FFR parameters that can be used in the system design of these networks.

Homogeneous Poisson point process and hard core Po
no vote
Application background Heterogeneous cellular networks (HetNets), which serve as an integral part of the Third Generation Partnership Project (3GPP) Long Term Evolution (LTE) specification, have emerged as a promising solution to cater to the explosive rise in the number of portable handheld devices and the growing demand for media-rich wireless data services. In general, HetNets consist of a macro tier comprising large scale macrocells, where each macrocell is overlaid with multiple tiers of small cells (e.g. picocells, femtocells). This configuration allows the available spectrum to be reused more frequently by supporting a high number of short to medium range transmissions while enhancing the spectrum efficiency (SE) performance, defined as the total throughput achievable per unit bandwidth utilized. On the downside, more frequent spectrum reuse leads to increased levels of inter-cell interference (ICI) which, when uncontrolled, can severely undermine the overall

Macrocell and Femtocell
4.3
Macro and Femto cells are combinally deployed to enhance users capacity and to utilize spectrum efficiently. A  macrocell  is a cell in a mobile phone network that provides radio coverage served by a high power cellular  base station (tower). Generally, macrocells provide coverage larger than microcell.  The antennas for macrocells are mounted on ground-based masts, rooftops and ot

Poisson Point Process and Voronoi diagram
4.0
PPP_Vor code is used to minimize intercell and intra cell interference for co channel. Poisson point process is a particular kind of random process by which a set of isolated points are scattered about a line or a plane or a three-dimensional space or any of various other sorts of spaces. Often the term poisson process is used to mean a Poisson point process in which the space in which isolated points are randomly scattered is a line, which in many applications represents time. a Voronoi diagram is a partitioning of a plane into regions based on distance to points in a specific subset of the plane. That set of points (called seeds, sites, or generators) is specified beforehand, and for each seed there is a corresponding region consisting of all points close to that seed than to any other. These regions are called Voronoi cells. The Voronoi diagram of a set of points is duel to its delanuay triangulation. Put simply, It's a diagram created by taking pairs of poi
