【摘要】：针对基于无线信道特征的密钥提取技术中传统双门限量化的量化门限选取适应性不强的问题,提出了信道特征相关性的概念和量化因子门限控制的方法,通过信道特征相关性系数与信噪比对量化因子进行调节,以提高量化门限适应性。仿真结果表明,与传统的双门限量化相比,该方案可达到更高的精度,能够有效提高信道特征提取量化的一致性。
[Abstract]:In this paper , the concept of channel characteristic correlation and the method of threshold control of quantization factor are proposed for the traditional double threshold quantization threshold selection in key extraction technology based on wireless channel characteristics . The quantization factor is adjusted by the correlation coefficient of channel characteristics and the signal to noise ratio to improve the quantization threshold adaptability . Simulation results show that the scheme can achieve higher accuracy compared with the traditional double threshold quantization , and can effectively improve the consistency of the channel feature extraction quantization .
