| 摘 要： | 在对短波信道仿真模型进行了深入分析,并对非正弦时域正交信号的调制解调原理进行研究的基础上,利用Simulink软件对短波信道进行了仿真实现,构建了基于PSWF的非正弦时域正交信号的调制端和解调端。采用一种新的重构方法使小相对带宽PSWF脉冲的产生摆脱了Toeplitz矩阵求解的限制。在3~3.003 MHz频段内,实现了数据流的动态仿真。最后,给出了不同调制路数下的误码率曲线。 |

| Abstract: | A model was set up based on Simulink in this paper, on the conditions of analysis of the model of HF Channel and the principle of the non-sinusoidal time-domain orthogonal modulation and demodulation. A reconstructing method was used for producing PSWF in a small relative bandwidth with getting rid of the limits of the Toeplitz matrix. The Dynamic simulation was realized in the frequency between 3-3.003 MHz. The relations of the BER and the modulation lines were given at last. |
