AI中文摘要:
本补充材料提供了脉冲式空间随机化加密感知的信噪比损失(SNRL)分析的完整数学推导。我们首先推导了一个简化模型,其中发射端随机化由独立同分布的复空间系数表示。基于该模型,我们建立了几乎必然和均值的渐近SNRL,推导了有限相干处理间隔(CPI)下的前导偏差和方差,并为独立伯努利单元激活获得了闭式系数矩和渐近SNRL。这些结果补充了相关论文中的简明陈述和证明草图。
英文摘要:
This supplementary material provides the complete mathematical development for the signal-to-noise ratio loss (SNRL) analysis of pulse-wise spatially randomized encrypted sensing. We first derive a reduced model in which the transmit-side randomization is represented by an independent and identically distributed complex spatial coefficient. Based on this model, we establish the almost-sure and mean asymptotic SNRL, derive the leading bias and variance for a finite coherent processing interval (CPI), and obtain closed-form coefficient moments and asymptotic SNRL for independent Bernoulli element activation. These results complement the concise statements and proof sketches in the associated paper.
