	abstract = {This paper investigates the intercept probability (IP) performance for a dual-hop multi-secondary user (SU) underlay cognitive-radio networks. Whereby, the relay R is self-powered by harvesting energy from secondary sources using the time switching variant (TS) of simultaneous wireless information and power transfer (SWIPT) protocol. Single-antenna SUs are transmitting data to multi-antennas end-user D, performing maximal-ratio combining (MRC) diversity technique, through R in presence of (i) a primary network composed of a primary transmitter (PUt) and receiver (PUr) pair, and (ii) a passive eavesdropper at each hop (i.e., E1 and E2), attempting to overhear the communication. Moreover, we suppose that the second eavesdropper has multiple antennas and employs the MRC technique, that the relay employs the Decode-and-Forward relaying protocol, that the two hops are subject to the Rayleigh fading model, and that the channel state information is fully known at both D and E2. Because of the underlying strategy, the SUs are constantly modifying their transmit powers to prevent interference with primary users. A closed-form expression of the IP is obtained by taking into consideration the correlation between the secrecy capacities for both hops. The impact of other essential factors on IP, such as the transmit power of sources, the fading severity parameter, and the maximum tolerable interference power (MTIP), is also investigated. Specifically, we want to know if the energy harvester (i.e., relay) might improve the security of such a system even more for low MTIP or transmit power of SUs. Monte Carlo simulations verify all of the obtained results, and valuable insights into the secrecy of the considered system are achieved. IEEE},

	abstract = {We investigate the sum rate performance of a generalized space shift keying (GSSK)-aided, non-orthogonal multiple access (NOMA) network. In particular, we consider a multiple-input multiple-output (MIMO) NOMA downlink channel, where the base station employs GSSK modulation to transmit additional information to the NOMA users. We present a novel energy-based maximum likelihood (ML) detection strategy at the NOMA users to decode the active antenna indices. We derive a closed-form expression for the average pairwise error probability of the energy-based ML strategy to find a union bound on the bit error probability. Further, we derive the expression for the overall sum rate of the proposed GSSK-aided MIMO-NOMA system. Through numerical evaluations, we show that the proposed system outperforms the conventional MIMO-NOMA system, in terms of spectral efficiency. {\textcopyright} 1967-2012 IEEE.},
