Secure Spatial Modulation With a Full-Duplex Receiver

Chaowen Liu, Lie-Liang Yang, Wenjie Wang

IEEE Wireless Communications Letters > 2017 > 6 > 6 > 838 - 841

We propose and investigate a full-duplex receiver assisted secure spatial modulation (FDR-SSM) scheme, whose security is enhanced by the jamming sent from a full-duplexing legal receiver. In our FDR-SSM system, jamming signals are designed to allow the legal receiver free from self-interference, while imposing time-varying interference on the passive eavesdropper. Therefore, the FDR-SSM scheme can...

Carrier Frequency Offset Estimation in Uplink OFDMA Systems: An Approach Relying on Sparse Recovery

Min Huang, Lei Huang, Chongtao Guo, Peichang Zhang, more

IEEE Transactions on Vehicular Technology > 2017 > 66 > 10 > 9592 - 9597

This paper proposes a novel blind carrier frequency offset (CFO) estimator, namely the sparse recovery assisted CFO (SR-CFO) estimator, for the uplink orthogonal frequency-division multiple access (OFDMA) systems. By exploiting the sparsity embedded in the OFDMA data, the CFO estimation is formulated as an optimization problem of sparse recovery with high-resolution. Meanwhile, in order to enhance...

Piecewise Companding Transform Assisted Optical-OFDM Systems for Indoor Visible Light Communications

Hongming Zhang, Lie-Liang Yang, Lajos Hanzo

IEEE Access > 2017 > 5 > 295 - 311

In visible light communications (VLCs) relying on intensity-modulation and direct detection (IM/DD), the conversion from electrical signals to optical signals and the limited dynamic range of the light-emitting diodes (LEDs) constitute the fundamental impediments in the way of high-integrity communications, especially when orthogonal frequency-division multiplexing (OFDM) is employed. In IM/DD VLCs,...

Discrete Multi-Tone Digital Subscriber Loop Performance in the Face of Impulsive Noise

Tong Bai, Hongming Zhang, Rong Zhang, Lie-Liang Yang, more

IEEE Access > 2017 > 5 > 10478 - 10495

As an important solution to “the last mile” access, digital subscriber loops (DSLs) are still maintained in a huge plant to support low-cost but high-quality broadband network access through telephone lines. The discrete multi-tone (DMT) transmissions constitute a baseband version of the ubiquitous orthogonal frequency division multiplexing. While the DMT is ideally suited to deal with the frequency...

Delay and Throughput Analysis of Cognitive Go-Back-N HARQ in the Face of Imperfect Sensing

Ateeq Ur Rehman, Lie-Liang Yang, Lajos Hanzo

IEEE Access > 2017 > 5 > 7454 - 7473

To mitigate spectrum scarcity, the cognitive radio (CR) paradigm has been invoked for improving the overall exploitation of the licensed spectrum by identifying and filling the free spectrum holes without degrading the transmission of primary users (PUs). Hence, we conceive a CR communication scheme, which enables a cognitive user (CU) to sense the activity of the PUs over a primary radio (PR) channel,...

Energy Dissipation Versus Delay Tradeoffs in a Buffer-Aided Two-Hop Link

Chen Dong, Li Li, Bo Zhang, Lie-Liang Yang, more

IEEE Transactions on Vehicular Technology > 2016 > 65 > 10 > 8060 - 8071

Our motivation is to characterize the hitherto unexplored tradeoff between energy dissipation and delay in a buffer-aided two-hop link. First, the optimality of 2-D Transmission Activation Probability Space (TAPS) partitioning is formally shown both in the presence and absence of an outage region. Then, the relationship between packet energy dissipation and block delay is found, which is established...

Bidirectional Worst Subchannel Avoiding Versus Best Subchannel Seeking Subcarrier-Allocation in Downlink OFDMA Systems

Jia Shi, Lie-Liang Yang

IEEE Transactions on Vehicular Technology > 2016 > 65 > 9 > 7160 - 7172

In this paper, we design and investigate two subcarrier-allocation algorithms for downlink orthogonal frequency-division multiple-access (OFDMA) systems. One is designed to avoid assigning users, by as many as possible, worst subchannels, which is referred to as the bidirectional worst subchannel avoiding (BWSA) algorithm. The other one is called the best subchannel seeking (BSS) algorithm, which...

Diffusion-based molecular communications: Inter-symbol interference cancellation and system performance

Lu Shi, Lie-Liang Yang

2016 IEEE/CIC International Conference on Communications in China (ICCC) > 1 - 6

2016 IEEE/CIC International Conference on Communications in China (ICCC)

We first compare the performance of the diffusion-based molecular communication (DMC) systems employing respectively the on-off keying (OOK), whose demodulation depends on a non-zero threshold, and the binary molecular shift keying (BMSK). Our studies demonstrate that the OOK is hard to operate in practical DMC environments, while the BMSK is more feasible for implementation in practice. Furthermore,...

Buffer-aided relaying for the multi-user uplink: outage analysis and power allocation

Bo Zhang, Chen Dong, Jing Lei, Mohammed El-Hajjar, more

IET Communications > 2016 > 10 > 8 > 936 - 944

In this study, the authors consider a two-hop network, where multiple source nodes (SNs) transmit to a destination node (DN) with the aid of a relay node (RN). The RN is equipped with a buffer, which is capable of storing multiple frames received from the SNs. During each time slot, the proposed protocol activates either the SN–RN hop or the RN–DN hop, depending on the channel quality of each hop...

Joint Space-Shift Keying and Orthogonal Shift-Keying Modulation for Energy-Efficient Signal Transmission

Lie-Liang Yang, Jingru Chen

2016 IEEE 83rd Vehicular Technology Conference (VTC Spring) > 1 - 5

2016 IEEE 83rd Vehicular Technology Conference (VTC Spring)

We propose a novel spatial modulation (SM) scheme, which is a joint of two index modulation schemes. One is the M-ary spatial shift-keying (MSSK) modulation operated in the space domain, while the other one is the M-ary orthogonal shift keying (MOSK) modulation, which usually requires more bandwidth to implement, when its modulation level increases. As both MSSK and MOSK belong to the energy-efficient...

Ateeq Ur Rehman, Lie-Liang Yang, Lajos Hanzo

2016 IEEE 83rd Vehicular Technology Conference (VTC Spring) > 1 - 5

2016 IEEE 83rd Vehicular Technology Conference (VTC Spring)

In this paper, we propose a cognitive Go-Back-N Hybrid Automatic Repeat reQuest (CGBN-HARQ) scheme for a cognitive radio (CR) system to opportunistically transmit data over a primary radio (PR) channel. We model the activity of PR users (PRUs) occupying the PR channel as a Markov chain with two states: `ON' and `OFF'. In order to use the PR channel, the CR system first senses the availability/unavailability...
