关于非高斯类噪声调制系统的进一步研究

Further Study on the Non-Gaussian Noise-like Modulation System

在Cek提出的调制系统上,对非高斯类噪声调制系统的作了进一步研究。解决了原系统模型中未解决的关于类噪声序列特征参数选择的问题,从而均衡系统的安全性与误码率。同时探讨了参数间距选择、随机序列长度选择对系统数据传输质量的影响,并通过仿真得出最适宜参数。最后,对最优参数系统在加性高斯白噪声信道下的误码率性能进行了仿真。仿真结果表明,此系统误码率性能良好,系统具有现实意义。

Based on the communication scheme proposed by Cek, a further study on non-Gaussian noise-like modulation system is made. The problem to select the characteristic parameters of noise-like sequences is solved, which balance the safety and bit error rate of the system. Meanwhile, the influences to transmission quality caused by the selection of different parameter spaces and bit lengths are discussed, and the optimum parameters of the system are derived. Bit error rate performance of the system with the optimum parameters in additive white Gaussian noise channel are simulated, and simulation results show that the parameters selected perform well, which demonstrates that the system is practical.
