Noise aggregation is an efficient way of aggregating the inherent noises introduced during wireless transmissions over multiple channels to degrade the eavesdropper's channel quality. While the performance of channel aggregation has not been thoroughly studied over wireless fading channels, we in this paper concentrating on analyses of its achievable average secrecy rate with emphasis on binary symmetric...
Guaranteeing the secure delivery is a critical yet challenging issue in wireless transmission. In this paper, a secure delivery scheme that utilizing the dynamic fountain code design is proposed. Using fountain-coded transmission, the transmitter continuously sends fountain packets until the legitimate receiver successfully recovers the original data from a sufficient number of fountain packets. Secure...
This paper presents a spectrally efficient distributed coded cooperation based on Opportunistic Relaying for multi-relay. The proposed scheme chooses the best relay to participate in the cooperation depending on the instantaneous channel information. We adopt distributed Rate-compatible punctured convolutional code. The relay operates on DF mode. After the single relay has been chosen, the best relay...
