This paper studies the secrecy outage probability of hybrid relay selection scheme which switches between full-duplex and half-duplex mode. First, motivated by the fact that either the full-duplex or half duplex has its own disadvantages, i.e., the full- duplex suffers from inherently self-interference even after cancellation by advanced technology while half-duplex cannot receive and transmit data...
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 investigates the joint optimization of multiuser packet scheduling and wireless resource allocation for video communications over downlink orthogonal frequency-division multiple-access (OFDMA) systems. The objective is to maximize the expected video quality of all mobile users under the wireless resource and delay-bound constraints. We formulate a quality-driven cross-layer problem to jointly...
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...
