| 摘 要： | 对AWGN和Rayleigh信道衰落下K-QCAM系统性能进行了研究,分析了K-QCAM系统对不同K值在一定的信噪比下系统性能和信道的关系,并推导出零均值Logistic映射的QCAM系统在不同衰落信道中的误比特率的表达形式。仿真结果表明,在相同的传输信道和信噪比条件下,仿真结果与理论值有很好的吻合性。

| Abstract: | The performance research of K-QCAM system was conduced under the AWGN and the Rayleigh fading channel. The performance and channel relations of the K-QCAM system to the different K value under certain signal-to-noise ratio were analyzed, and the error bit rate expression form of QCAM system with zero mean Logistic mapping under the many kinds of fading channels was deduced. The simulation result indicates that, in the same transmission channel and under the signal-to-noise ratio condition, the simulation result fits the theoretical value quite well. |
