Abstract: A Building Information Modeling (BIM)-based intelligent drafting method for prefabricated buildings includes the following steps: step 1: extracting building model information; step 2: modeling the building model information, where Revit elements are divided into model elements, datum elements, and view-specific elements; step 3: extracting element management information based on a BIM model; step 4: extracting a sub-model view based on a BIM global model; step 5: performing BIM-based three-dimensional (3D) parametric modeling; and step 6: performing intelligent drafting for the prefabricated buildings: extracting structure information by an integrated platform for production, sales, and construction of the prefabricated buildings, extracting architectural, structural and mechanical electrical BIM models and generating drawings with a quick response (QR) code.

Abstract: A method of canceling co-channel interference of a signal received by a mobile station having at least two receiving antennas, in a cellular OFDMA-TDD communication network having a serving base station and at least one interfering base station. The signal is a result of a serving signal transmitted by the serving base station which is distorted by at least one interfering signal transmitted by the interfering base station. The serving signal is transmitted with a first modulation scheme and the interfering signal is transmitted with a second modulation scheme. The method includes: a channel estimation phase delivering channel estimations of the serving signal and the interfering signal; and a MIMO detecting phase, detecting symbols by using the channel estimations of the serving signal and the interfering signal. The MIMO detection phase is realized using a non-linear method which uses the first modulation scheme and the second modulation scheme.
