摘　　要：研究了新型多载波传输技术———滤波多音频 (FMT)的滤波器组调制技术 ,通过滤波器的多相分解得到FMT系统的高效实现方法 ;对滤波器组中原型滤波器提出了主要性能指标和设计方法 。The design of filter banks in filtered multitone modulation (FMT) which is a new multicarrier transmission technique was researched. An efficient implementation of FMT based on linear-phase FIR filter is derived by the polyphase representation of FIR. The main performance indices and design methods of prototype proposed, the performances of designed prototypes which were applied to the FMT system were studied in wireless channel.
