| 摘 要： | 针对变换域通信系统现有调制方式频谱效率较低的情况,提出了在变换域通信系统中实现QAM调制(TD-QAM)的方法。基于MATLAB,验证了TD-QAM的正确性,仿真了TD-QAM在部分频带干扰下的性能。结果表明,所提出的TD-QAM差错概率与常规数字QAM调制一致,同时具备较强的抗部分频带干扰的能力。

| Abstract: | A QAM realization method in transform domain communication system(TDCS) is proposed to increase the spectrum usage.The effectiveness of realizing TD-QAM is demonstrated by simulating with MATLAB,and the interference suppression performance in partial bands jamming is simulated.The result shows that TD-QAM can effectively increase the spectrum usage,while obtaining the ability to interference suppression. |
