摘要:【中文】一种基于alpha稳定分布随机过程偏斜度参数的隐蔽通信方法,以有偏斜的alpha稳定分布随机序列作为载波,合法用户传输的隐蔽比特来调制前后半个比特周期载波序列的偏斜度极性,使之绝对值相同但极性相反,因此整个比特周期的隐蔽信号呈现出对称alpha稳定分布的特点;这种方法发射的隐蔽信号,与许多无线通信网络中存在的对称alpha稳定分布干扰非常相似,从而使得窃听者不易察觉到隐蔽通信的存在。本发明给出了计算量非常小的偏斜度的估计公式,以及推导出了相应的概率密度函数,得到了误比特率公式,指出了误比特率与特征指数、偏斜度、和样本数之间的关系。本发明实现容易、对设备计算性能要求不高的,隐蔽性较好。 【EN】A hidden communication method based on skew parameters in an alpha stable distribution random process is characterized in that a skewed alpha stable distribution random sequence is used as a carrier, and hidden bits transmitted by legal users modulate the skew polarity of the carrier sequence in the front half bit period and the back half bit period to make the absolute values of the carrier sequences identical but the polarities opposite, so that hidden signals in the whole bit period have the characteristic of symmetrical alpha stable distribution; the covert signal transmitted by this method is very similar to the symmetric alpha-stationary distributed interference present in many wireless communication networks, so that the presence of covert communication is not easily perceived by an eavesdropper. The invention provides an estimation formula of skewness with very small calculation amount and deduces a corresponding probability density function to obtain a bit error rate formula, and indicates the relationship between the bit error rate and the characteristic index, the skewness and the sample number. The invention has the advantages of easy realization, low requirement on the computing performance of equipment and better concealment.
