摘　　要：给出了滤波多音调制系统的原型滤波器优化设计方法.该方法不仅可以最小化原型滤波器的阻带能量,还界定了符号干扰功率、过渡带能量,适用于严格采样和非严格采样滤波多音调制系统.数值仿真结果表明该方法可以获得较好性能.An optimal design method for the prototype filter design of the filtered multitone modulation system is proposed. This method can not only minimize the stopband energy of the prototype filter, hot also determines the inter symbol interference power and the transition band energy, which can be used to design prototype filters for both the critically sampled FMT system and the non-critically sampled FMT system. Numerical simulation results show that the prototype filter can obtain a better performance by this method.
