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。 A QAM realization method in transform domain communication system(TDCS) is crease the spectrum usage. The effectiveness of realizing TD - QAM is demonstrated by 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.
