【摘要】 当前实现信号安全的要求主要是通过对信号的编码和加密方法来实现的,但是信号的隐蔽性却相对较弱。文中主要阐述了利用噪声特性来达到对信号隐蔽的目的,并讨论了该方法和其他信号加密方法的有效结合,及在特定情况下的应用和适应性。更多还原

【Abstract】 Today signal is sent by code algorithm to fit the safety requirement, but the signal is easy detected by the detector once a signal is sent,which hides the complexity of the signal is not so easy.In this paper,the main conception is introduced the way using noise character to hide the signal.Discusses the way bond with the other code means,the using with special environment,and the ability to fit different situation.更多还原
