Generalized frequency division multiplexing (GFDM) has been regarded as one of the promising candidates for the physical layer (PHY) of fifth generation (5G) wireless networks. Multiple-input multiple-output (MIMO) friendliness is a key ability for a physical layer scheme to match the foreseen requirements of 5G wireless networks. On the other hand, index modulation (IM) concept, which relies on conveying additional information bits through indices of certain transmit entities, is an emerging technique to provide better spectral efficiency. In this paper, a novel MIMO-GFDM system, which combines GFDM with space and frequency IM (SFIM) technique, is proposed. In the GFDM-SFIM scheme, the transmit antenna, the constellation mode and the classic constellation symbols are determined according to incoming bit stream. The main contribution of the paper is the construction of the GFDM-SFIM system model including joint MIMO detection and GFDM demodulation performed by the GFDM-SFIM receiver. We evaluate the error performance of the GFDM-SFIM scheme as well as prove its superiority by making comparisons with the spatial modulation (SM) GFDM system and orthogonal frequency division multiplexing (OFDM) SFIM system for Rayleigh multipath fading channels.

Being very resilient devices, smart cards have been commonly used for two-factor authentication schemes. However, the possibility of side-channel attacks renders private data stored in the cards vulnerable to compromise. With this in mind, we propose an authentication protocol that incorporates a second factor, which is as a password, in addition to the smart card. The scheme is aimed to withstand most common security breaches as well as compromised smart card scenarios and offline dictionary attacks on the passwords. Details of a reference implementation are also given along with performance evaluation of the proposed protocol comparing to the literature. Performance analyses show that the proposed protocol outperforms existing solutions in the literature. Moreover, the computational cost of the proposed protocol is less than 2 seconds on our reference implementation that uses commercially available smart cards.

In this paper, we present the design and implementation of a software defined orthogonal frequency division multiplexing (OFDM)-based underwater acoustic (UWA) communication system with link adaptation. Our system implementation is based on the customized versions of National Instruments Universal Software Radio Peripheral (USRP). The modified USRPs are interfaced with hydrophone front-ends for acoustic transmission. We investigate the performance of various adaptive algorithms where both modulation order/type and power on each subcarrier are selected based on channel conditions in order to maximize throughput. The experimental in-pool test results verify the superiority of adaptive transmission.

Software Defined Networking (SDN) is a new paradigm proposed to meet the requirements of new networking concepts such as cloud computing and data center networking. SDN decouples control and data planes and uses a logically centralized controller to manage the underlying network resources. In this paper, a joint server and route selection mechanism is proposed for SDN networks, where current and past statistics of network resource utilization are taken into account to allocate a server and a corresponding routing path for each incoming flow. The proposed mechanism periodically and automatically updates the link cost metrics of link state routing protocol to achieve the load balancing in the network. The proof of concept has been implemented using Mininet to emulate OpenFlow enabled switches and OpenDaylight as an SDN controller. Using the real IP traffic, we successfully demonstrated that the proposed system evenly distributes traffic flows among network links and servers.

This paper investigates the implementation of complex field network coding (CFNC) technique in two-way relay networks. The application of convolutional channel codes with two different decoding schemes is also studied in the given setup. Two source nodes use the same convolutional code and both decoding schemes are based on Viterbi algorithm (VA). The first decoding method combines trellis structures of the convolutional codes, employed at both sources, and utilizes VA for decoding at relay. Since this method has high complexity, a second method with reduced complexity is suggested. The second method performs a sub-optimal decoding metric calculation followed by a disjoint channel decoding for the two sources. Bit error ratio simulations are performed for both decoding schemes in Rayleigh and Nakagami-m fading environments. Simulation results indicate that the reduced complexity decoding provides the same diversity gain as the joint full state decoding with negligible loss in performance.

Generalized frequency division multiplexing (GFDM) is considered as a candidate waveform for 5G wireless communication systems. It is the generalize form of the orthogonal frequency division multiplexing (OFDM) that includes a number of subcarriers and subsymbols. An alternative waveform referred as the superimposed waveform in this study, was recently proposed to increase the data rate. The superimposed waveform is based on using orthogonal polynomial in each grid of time-frequency lattice structure. In this way, more than one symbols are transmitted with the different orthogonal pulses. While the proposed waveform showed promising results for the increasing data rate, there were some issues regarding the implementations. Motivated by this, we design transceiver structure as a low complex way with mathematical derivation by using inverse discrete Fourier transform (IDFT) and DFT operations. The bandwidth efficiency is almost 2.4 much higher than GFDM with Gaussian pulses. The performances of the superimposed waveform over a Rayleigh Fading channel and its comparison over additive white Gaussian noise (AWGN) channel are done.

SU-PhysioDB can be used to evaluate the performance of the security mechanisms designed for the communication among the biosensors within Body Area Networks (BANs). We present a detailed description of our SU-PhysioDB database along with providing a performance comparison of two specific physiological parameter generation techniques using a public database and our SU-PhysioDB da-tabase.

This paper is concerned with the performance analysis of a dual-hop random access network in underwater communication environment. Single gateway equipped with multiple antennas, and employing zero-forcing technique in a space division multiple access scenario, is connected a random number of independent sources which are hidden from their destination(s). The sources are located underwater, and the only mean to connect them with their destination(s) is through a gateway, which acts as amplify and forward relay. We developed accurate mathematical models for the multiple access interference which take into account, in addition to the statues of each source (active/idle), the effects of fading and additive noise at both the gateway and destination(s). A new unified mathematical method is developed, which leads to the derivation of new analytical expressions for the overall spectral-efficiency. The accuracy of the new mathematical results is confirmed by Monte Carlo simulation.

Cellular systems of fifth generation (5G) require a waveform with flexible guard interval length along with a low power consumption. Different cyclic prefix (CP) durations in long term evolution (LTE) result in loss of orthogonality between transmitted symbols and cause interference. In addition, CP-based waveforms consume more power for CP part. “Zero tail DFT-spread OFDM” (ZT DFT-s-OFDM) and “DFT-spread zero word OFDM” (DFT-s-ZW-OFDM) have been proposed recently with flexible guard intervals as a portion of the modulated signal. However, ZT DFT-s-OFDM suffers from intersymbol interference because of imperfect zero tails. On the other hand, although DFT-s-ZW-OFDM has a superior performance in multipath channels, it consumes more power than ZT DFT-s-OFDM. In this paper, we utilize the similarity between the transceivers of these two waveforms to propose an orthogonal hybrid waveform. The hybrid waveform has high flexibility in order to control the symbol power and bit error rate (BER) performance of the system along with having flexible guard interval. The complexity of the proposed hybrid waveform is the same as ZT DFT-s-OFDM and DFT-s-ZW-OFDM.

In this paper, a new multiple-input multiple-output (MIMO) transmission technique, which is called space-time quadrature spatial modulation (ST-QSM), is proposed. The ST-QSM scheme aims to provide a diversity gain for quadrature spatial modulation (QSM) by combining it with the Alamouti or ABBA space-time block codes (STBCs). In the ST-QSM scheme, the transmit antennas are subdivided into two groups and the information is conveyed with the indices of the antennas in these groups, in addition to the two complex modulated symbols. These two complex symbols are decomposed into their in-phase and quadrature components and independently transmitted through their corresponding active transmit antennas, whose indices are determined from the first and the second groups. Then, the Alamouti's STBC or ABBA STBC principle is applied to each group depending on the number of antennas in them. The superior error performance of the proposed ST-QSM scheme is shown by computer simulations compared to QSM, Alamouti's STBC and space-time block coded spatial modulation (STBC-SM) schemes. In addition, the pairwise error probability (PEP) of ST-QSM is derived and the average bit error probability (ABEP) over uncorrelated Rayleigh fading channels is obtained for different MIMO configurations.
