摘要

PURPOSE: A network coding method and a system considering a difference of channel state of receivers are provided to enhance effectiveness of broadcasting than an existing network coding by applying a coding method considering a difference of channel state of receivers.;CONSTITUTION: A transmitter receives information about channel environment form a plurality of receivers(A,B). The transmitter broadcasts a packet in receivers in which channel environment is different among a plurality of receivers. The receivers receiving the broadcasted packet respectively demodulate with different modulation order. A second receiver demodulates a packet with a second modulation order. A first receiver demodulates with a first modulation order in which bandwidth is small than the second modulation order.;COPYRIGHT KIPO 2011
