DATA RECEIVING DEVICE FOR RECEIVING DATA FRAMES USING CONSTELLATION MAPPING AND DATA TRANSMISSION DEVICE FOR TRANSMITTING THE DATA FRAMES

摘要

PURPOSE: A data receiving device and data transferring device transmitting a data frame are provided to distinguish data frame by constellation mapping schema to each data frame through a data receiving device. CONSTITUTION: A constellation mapping unit(510) applies a first constellation mapping scheme to a first data frame. A transmitting unit(520) transmits the first data frame to a data receiving unit(540). The data receiving unit receives the first data frame. The data receiving unit receives a second data frame from a second transmitting device. The data receiving device distinguishes the second data frame and the first data frame according to each constellation mapping technique.
