In this paper, by applying Turbo principle to convolutionally coded synchronous multi-carrier DS-CDMA, we propose Turbo parallel interference cancellation and decoding, which is termed Turbo PIC/decoding. We make analysis and simulations for Turbo PIC/decoding by the computer. The simulation results show that Turbo PIC/decoding acquires better performance(More)
The paper reviews the current status of Educational Decision-Making System, and introduces a GIS-Based Educational Decision-Making System (BHEDSS) developed by the Graduate School of Education in Peking University. BHEDSS has been put into application for over two years, and the user feedback is positive. It combines higher education research information(More)
