摘要
在分析滤波多音调制 (FMT)的基本原理和优点的基础上 ,给出了一种基于线性相位FIR滤波器的FMT实现方案 ,并对该方案的实现复杂度做了讨论 .数据表明 ,这种实现方案简单 ,有效地缩小了FMT和OFDM在系统复杂度上的差距 .
The basic theory and advantages of filtered multitone modulation (FMT) are studied. An efficient implementation of FMT based on linear-phase FIR filter is proposed and its complexity is discussed. The result shows that this method can simplify the FMT structure and shortens the gap between FMT and OFDM systems in terms of complexity.
