摘要/Abstract

摘要： 提出了一种基于滤波多音（FMT）系统的自适应比特分配算法，在发射端等功率发射的基础上，通过测量每个子载波的信号失真比（SDR），确定每个子载波的比特分配方式和传输参数. 仿真结果表明，该算法提高了FMT系统的抗衰落性能.

关键词: FMT, 自适应调制, SDR

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.

Key words: signal distortion ratio , adaptive modulation, FMT
