Preamble detection before data transmission is an important module for an underwater communication system, since false detections would bring undesirable consequences in terms of the lifetime and coexistence of underwater networks. This paper conducts a thorough investigation of preamble detection in adverse underwater acoustic channels in the presence of various external interference, such as narrowband interference, impulsive noise, partial-band partial-block-duration interference, and chirps ...

Non-orthogonal multiple access (NOMA) has recently attracted a lot of attention as a promising multiple access technology to be used in the fifth generation (5G) cellular networks. In this study, the authors investigate uplink NOMA transmissions in a cooperative cellular network in the presence of frequency selective multipath fading channels. Specifically, two users communicate with the base station simultaneously with existence of a half-duplex relay employing the decode-and-forward scheme to ...

Non-orthogonal multiple access has recently emerged as a promising multiple access technique for future wireless technology. In this study, the authors investigate superposition coding in a downlink cooperative cellular system based on the orthogonal frequency division multiplexing (OFDM) modulation in the presence of frequency selective multipath fading channels, a setup that has not been studied before. Specifically, the base station communicates with two paired mobile users simultaneously via...

This paper considers a two-hop network consisting of a source, two parallel half-duplex relay nodes, and two destinations. While the destinations have an adequate power supply, the source and relay nodes rely on harvested energy for data transmission. Different from all existing works, the two relay nodes can also transfer their harvested energy to each other. For such a system, an optimization problem is formulated with the objective of maximizing the total data rate and conserving the source a...

The ultra-dense network (UDN) has been identified as an appealing solution to address the huge service demands in future 5G and beyond. In this paper, we propose an optimization design of UDN balancing user mobility and network densification, where the massive users are divided into different groups according to their moving speeds, and different groups are served by different subnets. This way, the UDN can adjust subnet parameters to meet the service demands using minimum resource. Specifically...

In the future fifth generation communication systems, sparse code multiple access (SCMA) shows strong competitiveness as a novel non-orthogonal multiple access (NOMA) technique. Attributing to multi-dimensional codebooks, the SCMA can obtain shaping gain and provide a better performance than some other NOMA schemes, such as pattern division multiple access, low-density signature (LDS), and so on. However, under higher user load, each orthogonal resource in high-order SCMA systems is occupied by ...

This letter proposes a fractional sparse code multiple access (FrSCMA) system in which each user directly maps a varying number of error-correction coded symbols onto the resource elements per channel use. The dynamic sparse mapping leads to a fractional spreading factor, often smaller than that in the existing multidimensional constellation (MDC) mapping based sparse code multiple access (SCMA) approach. We develop a two-step optimization method to design the factor graph for maximizing the sum...

Underwater systems for ocean exploration and monitoring consist of a mix of geographically distributed stationary infrastructure and mobile units. The stationary infrastructure could be bottom-anchored nodes and surface buoys that are connected to a control center via cables and in-air radio links. Both the stationary and mobile units can be equipped with acoustic communication modules for underwater wireless data transmission. With the backbone (cable or radio) connection, those acoustic commun...

This paper studies a direct-sequence spread-spectrum communication system with a small spreading factor (e.g., a single digit) in underwater acoustic multipath channels. Exploiting the channel characteristics that the propagation paths can be grouped into distinct clusters, a receiver with a set of parallel branches is proposed, where per-survivor processing (PSP) is applied on each branch to deal with the signal from one cluster while explicitly treating the signals from other clusters as struc...
