1. A transmitting/receiving apparatus for packetizing input continuous data and transmitting the packetized data to another apparatus on a communication network, and receiving a packet transmitted from another apparatus, comprising:

  • a packet construction section for dividing the continuous data into a plurality of subpackets, and constructing a packet by concatenating the plurality of subpackets;

    a modulation transmission section for modulating the packet constructed by the packet construction section, and transmitting the modulated packet to another apparatus on the communication network;

    a training session execution section for checking channel conditions, when a predetermined condition is satisfied, by communicating with another apparatus, and changing a modulation rule used in the modulation transmission section so that a packet transmitted from the modulation transmission section is successfully transmitted to a transmission destination apparatus; and

    a subpacket transmission confirmation section for confirming whether or not a subpacket included in the transmitted packet is transmitted successfully to the transmission destination apparatus, wherein if the modulation rule is changed by the training session execution section;

    the packet construction section reconstructs a new packet by concatenating a subpacket, which is confirmed as an unsuccessfully-transmitted subpacket by the subpacket transmission confirmation section, with subpackets newly generated from the continuous data, and the modulation transmission section modulates the reconstructed new packet in accordance with the changed modulation rule, and transmits the modulated packet.
