Abstract
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.
