摘　　要：给出了滤波多音调制系统容量的理论分析,证明滤波多音调制系统的系统容量取决于其原型滤波器的特性.提出了基于滤波多音调制系统原型滤波器的设计准则.仿真实验表明滤波多音调制系统的容量在802.11a的环境下,未编码时系统可达到10 Mb/s的速率.The capacity of the filtered multitone modulation system is theoretically analyzed. It is shown that characteristics of the prototype filter mainly decide the system capacity. Design strategies of the prototype filter are presentod. Simulation results show that the achievable bit rates of the uncoding system could reach 10 Mbps under the circumstances that the capacity of filtered multitone modulation system is 802.11 a.
