摘要

物理层安全密钥容量受信道测量时差、终端移动和加性噪声等因素影响，在均匀散射环境中定量分析了上述因素对密钥容量的影响。在分析含噪窄带信道参数的时域统计特性的基础之上，推导了密钥容量时域闭式解，并且分别在均匀散射和非均匀散射环境中验证了推导结果的正确性和适用性。

Abstract

Physical layer secret key capacity was affected by time difference of channel sounding

mobility of terminals

and additive noise.Effects on the physical layer secret key capacity were quantitatively analyzed in the uniform scattering environment.Based on the time domain statistical characteristics of narrow band wireless channel parameters with noise

a closed-form solution to physical layer secret key capacity in the time domain was derived.Afterwards

simulations in the uniform and non-uniform scattering environment were carried out to demonstrate its validity and applicability

respectively.
