【Abstract】 An adaptive bit allocation algorithm was proposed in FMT system.Based on equal power transmission at the transmitter,the modulation code and transmission parameters on each per subcarrier were decided by SDR measurement at the receiver.The simulation result shows that the resistance ability to decay of FMT system is improved efficiently.更多还原
