| Abstract: | 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 presented.Simulation results show that the achievable bit rates of the uncoding system could reach 10 Mbps under the circumstances that the capacity of filtered mul-titone modulation system is 802.11a. |
| |
| Keywords: | filtered multitone modulation prototype filter achievable bit rate |
