Publication number: 20110083055Abstract: The present invention relates to a decoding method for a raptor codes using system, which is capable of improving performance of the system and limiting increase in the amount of computation by grouping variable nodes if raptor codes are unsuccessfully decoded, to thereby increase a conjecture efficiency of variable node values. The decoding method is capable of improving performance of the system by making it possible to achieve performance improvement and additional reduction of the amount of computation even under an application of MP decoding by grouping variable nodes whose values cannot be known when decoded, dividing groups of variable nodes into sub groups, and conjecturing and recovering the variable nodes in a manner to exclude sub groups which do not satisfy check node equation.Type: ApplicationFiled: October 16, 2009Publication date: April 7, 2011Applicant: MEWTEL TECHNOLOGY INC.Inventors: Jun HEO, Kwangseok NOH, Byung Gueon MIN

Publication number: 20100105316Abstract: A Multiple-Input Multiple-Output (MIMO) relay system is provided. The MIMO relay system performs signal processing to provide requested real data to at least one selected user mobile station sequentially connected to a first relay station located in a first cell and a second relay station located in a second cell using spare frequency capacity allocated to a first base station of the first cell instead of a second base station of the second cell that drops the requested real data due to its frequency capacity being exceeded, thereby improving reliability of seamless real data input/output in relay communication, reducing call drop probability, and raising availability of frequency capacity by automatically adjusting frequency capacity allocated between cells.Type: ApplicationFiled: October 23, 2008Publication date: April 29, 2010Applicant: NewTel Technology Inc.Inventors: DoHoon KIM, Young-Chai Ko, Byung Gueon Min
