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。
The performance of K-QCAM system under AWGN and Rayleigh channel fading is studied. The relationship between system performance and channel for K-QCAM at different signal-to-noise ratios is analyzed. A QCAM system with zero-mean Logistic mapping The expression of the bit error rate in different fading channels. The simulation results show that the simulation results agree well with the theoretical values under the same transmission channel and signal-to-noise ratio.
