| 摘 要： | 该文提出了一种采用复合调制方式的AM广播方案.在数字调幅广播的基础上,引入了一种窄带调制方式——最小附加波形键控,形成复合调制,充分利用了有限的频带资源.系统仿真结果表明,两种调制方式在一定条件下都能获得不错的误码率性能.

| Abstract: | A compound modulation scheme based on digital amplitude modulation broadcasting (DAMB) and very minimum additive waveform keying(VMAK) was discussed in the paper,which sufficiently utilized the limited AM bandwidth.Simulations show good BER performance of both modulation schemes under certain conditions. |
