Patent number: 8310951Abstract: Disclosed is a network coding method and system for receivers having a different channel state that may demodulate and extract a single coded packet using a different demodulation scheme according to a channel state of each receiver. The disclosed network coding method may use a different demodulation scheme to be suitable for a channel state of each receiver by applying a packet encoding scheme combined with a modulation scheme. When two receivers receive a network coded packet, a receiver having a poor channel state may receive a relatively small amount of information from the single packet compared to the other receiver having a relatively excellent channel state, but may enhance the reliability of packet reception. The other receiver having the relatively excellent channel state may decrease the reliability of packet reception, but may receive a relatively large amount of information.Type: GrantFiled: February 19, 2010Date of Patent: November 13, 2012Assignees: MMC Technology, Inc., Soongsil University Research Consortium Techno-ParkInventors: Young Han Kim, Hyo Gon Kim, Sang Ki Yun

Patent number: 8005001Abstract: A congestion-resilient link adaptation method is provided. The link adaptation method for selecting any one of modes having mapped transmission parameters includes the steps of: estimating a channel-induced error number indicating the number of channel-induced transmission failures in a current mode and comparing the estimated channel-induced error number with a mode-down threshold; and determining whether the mode-down is performed based on the comparison result. Thus, higher throughput can be achieved without use of additional hardware or protocols.Type: GrantFiled: June 4, 2007Date of Patent: August 23, 2011Assignee: Soongsil UniversityInventors: Sae Woong Bahk, Hyo Gon Kim, Sang Ki Yun, Kyu Young Choi, Young Han Kim
