Abstract

The paper studies covert communication over a continuous-time Gaussian channel. The covertness condition requires that the channel output must statistically resemble pure noise. When the additive Gaussian noise is “white” over the bandwidth of interest, a formal coding theorem is proven, extending earlier results on covert Gaussian communication in discrete time. This coding theorem is applied to study scenarios where the input bandwidth can be infinite and where positive or even infinite per-second rates may be achievable.

连续时间上的高斯秘密通信

抽象的

本文研究了连续时间高斯信道上的秘密通信。隐蔽条件要求通道输出必须在统计上类似于纯噪声。当加性高斯噪声在目标带宽上为“白色”时,就证明了形式编码定理,从而在离散时间内扩展了隐式高斯通信的早期结果。该编码定理适用于研究场景,其中输入带宽可以是无限的,并且可以实现正甚至无限的每秒速率。
