【摘要】：針對(duì)基于無(wú)線信道特征的密鑰提取技術(shù)中傳統(tǒng)雙門限量化的量化門限選取適應(yīng)性不強(qiáng)的問(wèn)題,提出了信道特征相關(guān)性的概念和量化因子門限控制的方法,通過(guò)信道特征相關(guān)性系數(shù)與信噪比對(duì)量化因子進(jìn)行調(diào)節(jié),以提高量化門限適應(yīng)性。仿真結(jié)果表明,與傳統(tǒng)的雙門限量化相比,該方案可達(dá)到更高的精度,能夠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 .
