Patent number: 8200147Abstract: A wireless communication system for geographically controlling a communication area includes an access point for communicating with a terminal in a first area, and a jammer for generating noise for intercepting communication between the access point and a terminal in a second area. A jamming boundary for dividing an area in which the terminal can communicate with the access point and an area in which the terminal cannot communicate with the access point in an area in which the first area and the second area are overlapped is formed, and the jamming boundary is formed by a ratio between power of a signal transmitted to the terminal by the access point and power of a signal of the noise.Type: GrantFiled: November 25, 2009Date of Patent: June 12, 2012Assignee: Korea University Industry and Academy Collaboration FoundationInventors: Hee-Jo Lee, Yu-Seung Kim, Hyogon Kim

Publication number: 20060215781Abstract: A method for detecting and decoding a signal in a communication system based on Multiple-Input Multiple-Output (MIMO)-Orthogonal Frequency Division Multiplexing (OFDM). A signal is received through multiple receive antennas. A decision error occurring at a symbol decision time is considered and a symbol is detected from transmitted symbols. Original data transmitted from the detected symbol is recovered. The performance of a coded bit system can be significantly improved using a new equalization matrix G considering a decision error.Type: ApplicationFiled: March 22, 2006Publication date: September 28, 2006Applicants: SAMSUNG ELECTRONICS CO., LTD., Korea University Industry & Academy Collaboration FoundationInventors: Dong-Jun Lee, In-Kyu Lee, Min-Young Ahn, Jong-Han Kim, Heun-Chul Lee
