Secure Audio Transmission Over Wireless Uncorrelated Rayleigh Fading Channel

Audio communications and computer networking play essential roles in our daily lives, including many domains with different scopes. Developments these technologies are quick. In consequence, there is a dire need to secure up date. This paper presents an efficient model for audio signal transmission over the wireless noisy uncorrelated Rayleigh fading channel. Also, performance of utilized multiple secret keys-based cryptosystem analyzed transformation domains. The discrete cosine transform (DCT), sine (DST), wavelet (DWT) investigated key-based cryptosystem. Simulation results show consistent proposed can be ranked concerning employed domain as DWT, DCT, DST techniques. simulation experiments proved that presented signals transmitted channel achieves reliable link utilizing combined multi security layers.
