COMMUNICATION SYSTEM USING HIERARCHICAL MODULATION SCHEME OR NETWORK CODING SCHEME

摘要

PURPOSE: A communication system using a network coding technique or a layer modulation technique is provided to efficiently use wireless resource by generating a relay packet by applying the network coding technique to a source packet or a target packet. CONSTITUTION: A packet receiver(1021) receives a source packet transmitted from a source node and a destination packet transmitted from a destination node. A packet generator(1022) applies the network coding technique to source and purpose packet and generates the relay packet. A packet transmitter(1023) transmits the relay packet with the source node and destination node.
