<p>Disclosed is a data communication system transmitting data using adaptive modulation at an acknowledged data transfer mode simultaneously. The present invention includes a first step of monitoring variation of radio environments by a receiving end receiving packets sequentially, a second step of determining a coding type to be varied in accordance with the variation of the radio environments in the receiving end so as to inform a transmitting end of the determined coding type, and a third step of forwarding sequentially the corresponding packets with a transfer rate in accordance with the determined coding type in the transmitting end.</p> |
