Abstract: PURPOSE: A method for detecting a signal by grouping a constellation group in a multi antenna system of a spatial multiplexing mode is provided to separate a tree searching step of a QR-decomposition with M-algorithm into partial detecting steps and perform the steps in parallel or repetitively, thereby reducing operation complexity. CONSTITUTION: A constellation group is a symbol candidate group. The constellation group is separated into partial groups by grouping. The feature of a QRDM(QR-decomposition with M-algorithm) is that a constellation group is separated into partial groups with the same cardinality. A tree search process of the QRDM is partially and multiply detected. A signal for performing the partial and multiple detection in parallel or repetitively is detected.

Abstract: A method for analyzing electro-optic characteristics in a grid computing environment are provided to shorten time needed for simulating the electro-optic characteristics such as resolution, contrast, color reproducibility, view angle, and response speed of an LCD device by using the grid computing environment. A structure of an LCD unit is laid out and mesh is formed to the generated structure for FEM(Finite Element Method)(120). Liquid crystal behavior distribution is analyzed by calculating physical effect of the liquid crystal according to applied voltage through the FEM(130). Electro-optic characteristics are analyzed by using generated liquid crystal behavior distribution analysis data. The liquid crystal behavior distribution analysis data is divided into the number of nodes defined by a user(200). The divided data is distributed to computer resources(210). Each computer analyzes the electro-optic characteristic by using liquid crystal behavior distribution analysis result data(220), and the result data is transmitted to a server computer(230). The server computer finishes the electro-optic analysis by verifying and merging the result data(250).

Abstract: PURPOSE: A signal detecting method for a multiple antenna system of a spatial multiplexing mode is provided to detect a signal by using QRD-M algorithm in which the upper limit and lower limit of complexity are limited. CONSTITUTION: If an accumulated matrix of saved branches is not higher than BabaiDist(S125), it is checked whether i=Ns or not(S130). If i=Ns and the number of residual branch is 1(S135), a Babai point is recognized as the best year(S140). If the accumulated matrix of saved branches is higher than BabaiDist, branches with higher matrix are removed. The residual branch is arranged on the basis of the accumulation matrix(S160). The best branch is saved as a solution of the ULBC (Upper-Lower Bounded-Complexity) QRD-M algorithm.
