We propose a new class of partially information-coupled (PIC) turbo codes to improve the transport block (TB) error rate performance for long-term evolution (LTE) systems, while keeping the hybrid automatic repeat request protocol and the turbo decoder for each code block (CB) unchanged. In the proposed codes, every two consecutive CBs in a TB are coupled together by sharing partial information bi... View full abstract»

Publication Year: 2018, Page(s):4414 - 4430
| | PDF (1699 KB) | HTML

In this paper, we investigate the performance of a two-way relaying (TWR) network with a battery-assisted energy harvesting (EH) relay. The relay uses limited battery energy to augment the harvested energy and aid communication between the two source terminals. Considering a time-switching relaying (TSR) protocol at the EH relay, we investigate the performance of the TWR system in terms of outage,... View full abstract»

• ### Full-Duplex Relay Selection in Cognitive Underlay Networks

Publication Year: 2018, Page(s):4431 - 4443
| | PDF (979 KB) | HTML

We analyze the outage and throughput performance of full-duplex relay selection (FDRS) in underlay cognitive networks. Contrary to half-duplex relaying, full-duplex relaying (FDR) enables simultaneous listening/forwarding at the secondary relay(s), thereby allowing for higher spectral efficiency. However, due to simultaneous source/relay transmissions in FDR, the superimposed signal at the primary... View full abstract»

• ### Partial Zero-Forcing for Multi-Way Relay Networks

Publication Year: 2018, Page(s):4444 - 4456

The ever increasing demands for mobile network access have resulted in a significant increase in bandwidth usage. By improving the system spectral efficiency, multi-way relay networks (MWRNs) provide promising approaches to address this challenge. In this paper, we propose a novel linear beamforming design, namely partial zero-forcing (PZF), for MWRNs with a multiple-input-multiple-output relay. C... View full abstract»

We consider a multi-way decode-and-forward relaying network with very large antenna arrays at the relay station. In this system, each user and the relay operate in half-duplex and time-division duplexing modes. To exchange information among all users, we propose a new transmission protocol which combines massive multiple-input multiple-output technology with linear processing, self-interference ca...

| | PDF (1880 KB) | HTML

This paper investigates the design and analysis of minimum mean square error (MMSE) turbo decision feedback equalization (DFE), with expectation propagation (EP), for single carrier modulations. Classical non iterative DFE structures have substantial advantages at high-data rates, even compared withturbolinear equalizers-interference cancellers (LE-IC), hence making turbo DFE-IC s...

Publication Year: 2018, Page(s):4498 - 4512
| | PDF (1260 KB) | HTML

We investigate lossy compressed sensing (CS) of a hidden, or remote, source, where a sensor observes a sparse information source indirectly. The compressed noisy measurements are communicated to the decoder for signal reconstruction with the aim to minimize the mean square error distortion. An analytically tractable lower bound to the remote rate-distortion function (RDF), i.e., the conditional re... View full abstract»

Publication Year: 2018, Page(s):4513 - 4520
| | PDF (892 KB) | HTML

We consider a communication channel where there is no common clock between the transmitter and the receiver. This is motivated by the recent interest in building system-on-chip radios for Internet of Things applications, which cannot rely on crystal oscillators for accurate timing. We identify two types of clock uncertainty in such systems: timing jitter, which occurs at a time scale faster than t... View full abstract»

• ### Power Allocation for Energy Efficient Multiple Antenna Systems With Joint Total and Per-Antenna Power Constraints

Publication Year: 2018, Page(s):4521 - 4535
| | PDF (1427 KB) | HTML

An energy efficiency (EE) maximization problem with multiple transmit antennas (multiple-input-single-output or distributed antennas setups) is considered in this paper. Besides the constraint on the total transmit power, per-antenna transmit power constraints, and a total weighted power constraint are jointly considered. Moreover, a quality-of-service constraint is also considered. Both linear an... View full abstract»

Recent studies have shown that carrier-aggregated multi-user (MU) multi-input-multi-output (MIMO) orthogonal frequency division multiplexing (OFDM) systems can deliver unprecedented improvements in network throughput and capacity when compared with existing systems. However, most of these studies fail to take into account the nonlinear constraints that limit the performance of such systems. This p... View full abstract»

Publication Year: 2018, Page(s):4550 - 4562
| | PDF (1017 KB) | HTML

The value of the channel state feedback becomes more significant in the upcoming 5G era due to the application of the millimeter-wave (mm-Wave) technologies in 5G. In the meantime, the feedback is challenging in the mm-Wave systems especially with massive MIMO antenna for two reasons: first, the channel states change faster at the millimeter band; second, in the massive antenna system, there are a...

• ### On the Performance of Multiuser MIMO Systems Relying on Full-Duplex CSI Acquisition

Publication Year: 2018, Page(s):4563 - 4577
| | PDF (1367 KB) | HTML

In this paper, we propose a combined full duplex (FD)- and half duplex (HD)-based transmission and channel acquisition model for an open-loop multiuser multiple-input multiple-output (MIMO) systems. Assuming residual self-interference at the base station (BS), the idea is to utilize the FD mode during the uplink (UL) training phase in order to achieve simultaneous downlink (DL) data transmission a...

• ### Optimization of the Cut-Off Rate of Generalized Spatial Modulation With Transmit Precoding

Publication Year: 2018, Page(s):4578 - 4595
| | PDF (1617 KB) | HTML

Spatial modulation (SM) and generalized spatial modulation (GSM) are emerging multiple input multiple output (MIMO) schemes that use transmitter (TX) antenna switching for data transmission. Their operating principle makes optimization of channel capacity and mutual information usually more difficult than for conventional MIMO schemes which are not based on antenna switching. We propose to use cha... View full abstract»

In this paper, we consider the two-user broadcast channel and we characterize its stable throughput region. We start the analysis by providing the stability region for the general case without any specific considerations on transmission and reception mechanisms. We also provide conditions for the stable throughput region to be convex. Subsequently, we study the case where the transmitter uses supe... View full abstract»

| | PDF (2467 KB) | HTML

We consider a wireless network where multiple energy harvesting transmitters communicate with the common receiver in a time-sharing manner. In each slot, a transmitter can either harvest energy or send its data to the receiver. Given a time deadline, the goal is to maximize the sum rate of transmitters under random energy arrivals with both perfect and imperfect channel state information at the re... View full abstract»

• ### Performance Analysis of Opportunistic Distributed Scheduling in Multi-User Systems

Publication Year: 2018, Page(s):4637 - 4652
| | PDF (1757 KB) | HTML

Consider the problem of a multiple access channel with a large number of users. In such a system, mostly due to practical constraints (e.g., decoding complexity), not all users can be scheduled together, and usually only one user may transmit at any given time. Assuming a distributed, opportunistic scheduling algorithm, we analyze the system’s properties, such as delay, QoS, and capacity scaling l... View full abstract»

Publication Year: 2018, Page(s):4653 - 4665
| | PDF (2097 KB) | HTML

Optical interconnects are emerging as a high bandwidth and low energy alternative to traditional electrical networks. However, most exiting designs put optical switching in the core layer due to issues, including limited scalability, potential bottleneck of the control plane, and high cost of the multi-wavelength switch. To this end, we propose Thor, a hybrid network architecture using optical int... View full abstract»
