ABSTRACT:
A TDMA radio communication system using a multiple subcarrier modulation method and comprising at least a first and a second radio station. The first radio station carries out communications by selectively modulating a subcarrier with which a desired transmission rate can be obtained in the second radio station, thereby providing a radio communication system that does not require the monitoring of each time slot by a terminal.
