Three dimensional map of different array structure
4.0
Application background Beamforming is one of the main branches of the array signal processing, can be widely used in the fields of radar, communication, sonar, navigation, speech signal processing, earthquake monitoring, geological exploration, radio astronomy and biomedical engineering, etc.. Key Technology beamforming, also known as spatial filtering. The time domain FIR filter is similar to that of linear filter. The array processing is a kind of spatial sampling and processing technology. ; the structure of the array is different, mainly divided into linear array, circular array, triangular array, L array, spherical array, etc..

Studio visual 2010 library management program
no vote
Application background Twenty-first Century is the information society, the information is the society's most important resources, will become the strategic resources to cause the people to pay close attention to. How to get the information? Books are our best way to get information, but because of the library books collection is greatly increased, so that the work of the traditional library is increasingly heavy. Forced people to use new management methods to manage the books, but how to relieve the librarian from the heavy work?With the rapid development of science and technology, human life has changed greatly, the rapid development of computer technology, so that all walks of life in the application of computer technology has been widely spread and use. The advent of the information age has become an irresistible trend, and human civilization is entering a new era. Therefore, library management system is also convenient, fast, low cost advantages are slowly into

Studio visual 2010 addition calculator based on MF
no vote
Application background With the development of science, the application of computer is becoming more and more extensive. It is bound to be a lot of computer language C++. C++ is one of the most widely used programming languages at home and abroad. It has the advantages of rich processing function, strong expression ability, convenient use, high efficiency and high efficiency. And C++ is a structured programming language; in addition, the functional structure of the C++ also provides a powerful guarantee for the realization of the modular design. So a lot of people are the preferred language for C++ programming. This course design is to use C++'s rich expression ability to write a simple calculator, the calculator of windows system to simulate simple calculation; in the design of the curriculum design requirements of the use of MFC to draw a calculator graphical interface, and guarantee the basic calculation. Key Technology The calculator is

Adaptive microphone beamforming
4.0
Application background Frequency invariant beamforming (Frequency-invariantBeamforming, FIB) is an important application in the acquisition and processing of the speech signal of the microphone array. The classical FIB design method is proposed in the model of far field plane wave. This paper presents the response variation spatial (SRV) Constrained Minimum (Linear) based on the near field spherical wave model.In the formation of Variance, LCMV, the spatial response function is used as the optimization condition, then the closed solution is obtained by the Lagrange multiplier method. However, the method is affected by the environmental interference and noise, and the value of the weight distribution needs to be floating. So this paper adopts the adaptive weighted frequency invariant wave velocity to form, which can adaptively select the weight value of the environment. Simulation examples demonstrate the validity of the proposed method and the correctness of theoret
