Implementation of information hiding at physical layer of wireless communication

Wireless communication plays a very important role in our daily life. Due to its vulnerability in resisting security attacks, it is extremely critical to ensure security when transmitting confidential data. The system must be designed in a way that those confidential data can be only retrieved by the intended user and this action will not affect the system’s normal performance. The capability to embed secret data with certain criteria is essential in the system. In this project, the implementation of such a scheme is presented. This scheme hides the secret data bits by using the variable pulse shaping filter. By adding the variable filter to the system, a noiseless, covertness, no degradation, transparent and less complex secret information hiding scheme can be achieved.
