Abstract

Due to the epidemic growing of telecommunication systems and new services, the demand for radio frequency spectrum has greatly increased to the extent that the radio frequency spectrum has been a vital source of value to radio communications. Therefore, managing the efficient use of the frequency spectrum of the different technologies and different services is very difficult. In the past, this was done by assigning afrequency spectrum for each service, But another way to solve this problem is based on the characteristics of a modulation that shares the frequency band without significant interference. This method is called spread spectrum modulation. Spread spectrum steganography method uses a spread spectrum communication concept in which a narrow- band signal is transferred into a pseudo-noise signal. This method shows a very high ability to withstand adverse interactions. It also has security advantages of the encryption based on the keys used in the production of different strings pseudo-random orthogonal - such as Gold strings. To spread the message signal spectrum, the Hadamard matrix is used with appropriate statistical properties of low cross-correlation. In this paper we have studied Steganography by Hadamard matrix and it is compared with a simple method.
