• ### Protograph-Based Interleavers for Punctured Turbo Codes

Publication Year: 2018, Page(s):1833 - 1844
| | PDF (2456 KB)

A method to design efficient puncture-constrained interleavers for turbo codes (TCs) is introduced. Resulting TCs profit from a joint optimization of puncturing pattern and interleaver to achieve an improved error rate performance. First, the puncturing pattern is selected based on the constituent code Hamming distance spectrum and on the TC extrinsic information exchange under uniform interleavin... View full abstract»

Incremental relaying is a spectral-efficient relaying approach which introduces itself as one of the possible solutions to the spectrum scarcity problem for future generations of cellular communications systems. In this paper, we study threshold amplify-and-forward incremental relaying for correlated fading channels, i.e., fading channels for which the channel gain amplitude varies during the time...

In this paper, we study the performance improvement methods for a cell-edge user of two-user non-orthogonal multiple access (NOMA) systems in downlink scenarios. To this end, we propose two cooperative relaying schemes, namely ON/OFF-full-duplex relaying (ON/OFF-FDR) and ON/OFF-half-duplex relaying (ON/OFF-HDR) schemes. More specifically, in order to improve the performance of the cell-edge user, ... View full abstract»

We consider a sum rate maximization problem with user scheduling in Gaussian MIMO broadcast channels, which is a combinatorial optimization problem. We transform it into a cardinality problem taking into account that selecting inactive users is equivalent to allocating zero power to unselected users. Then, we relax the cardinality constraint by introducing a penalty function to promote sparse powe... View full abstract»

Publication Year: 2018, Page(s):1940 - 1954

We study the cross-layer energy efficiency of cooperative MIMO networks. At the physical layer, the transmit power determines the outage probability and the number of contending nodes per unit area. At the medium access control (MAC) layer, accessing the channel takes additional time and energy, which impacts the throughput and the energy efficiency. Then, we propose a new cooperative MAC protocol... View full abstract»

• ### Design and Optimization of Differential Chaos Shift Keying Scheme With Code Index Modulation

Publication Year: 2018, Page(s):1970 - 1980
| | PDF (1439 KB)

Energy usage and data rate of differential chaos shift keying (DCSK) are both inefficient since half of the symbol duration is used to transmit reference. To improve the energy efficiency and data rate, we propose a new chaos modulation scheme which combines DCSK with code index modulation (CIM) referred to as CIM-DCSK. In the proposed scheme, a short reference signal is transmitted first. Then View full abstract»

• ### Constant-Composition Codes for Maximum Likelihood Detection Without CSI in Diffusive Molecular Communications

Publication Year: 2018, Page(s):1981 - 1995
| | PDF (1753 KB)

Instantaneous or statistical channel state information (CSI) is needed for most detection schemes developed for molecular communication (MC) systems. Since the MC channel changes over time, e.g., due to variations in the velocity of flow, the temperature, or the distance between transmitter and receiver, CSI acquisition has to be conducted repeatedly to keep track of CSI variations. Frequent CSI a... View full abstract»

Random linear network coding (RLNC) is a promising network coding solution when the network topology information is not fully available to all the nodes. However, in practice, nodes have partial knowledge of the network topology information. Motivated by this, we investigate the performance of RLNC and obtain different upper bounds on the failure probability of RLNC for the network constrained by ... View full abstract»

This paper investigates spatial-mode multiplexing (SMM) for practical free-space optical communication (FSO) systems using direct detection.

Publication Year: 2018, Page(s):2093 - 2106
| | PDF (1221 KB)

In a time-division duplex multiple antenna system, the channel state information can be estimated using reverse training. A pilot spoofing (contamination) attack occurs when during the training phase, an adversary (spoofer) also sends synchronized, identical training (pilot) signal as that of the legitimate receiver. This contaminates channel estimation and alters the legitimate beamforming/precod... View full abstract»
