Crest Factor Reduction in MC-CDMA Employing Carrier Interferometry Codes
EURASIP Journal on Wireless Communications and Networking - Tập 2004 - Trang 1-1 - 2004
Balasubramaniam Natarajan, Carl R Nassar
This paper addresses signal compactness issues in MC-CDMA employing carrier interferometry codes using the measure of crest factor (CF). Carrier interferometry codes, applied to -carrier MC-CDMA systems, enable users to simultaneously share the syst...... hiện toàn bộ
Radio resource management for OFDM-based dual-function radar-communication: sum-rate and fairness
EURASIP Journal on Wireless Communications and Networking - Tập 2024 Số 1
Jia Zhu, Yuanhao Cui, Junsheng Mu, Zexuan Jing, Xiaojun Jing
AbstractThis paper focuses on radio resource management (RRM) in multi-user dual-function radar communication (DFRC) systems using orthogonal frequency division multiplexing (OFDM) waveforms. We propose two RRM schemes, one from the perspective of sum rate maximization and the other from the perspective of user fairness maximization. These optimization problems are...... hiện toàn bộ
Coordinated movement of multiple mobile sinks in a wireless sensor network for improved lifetime
EURASIP Journal on Wireless Communications and Networking - Tập 2015 - Trang 1-16 - 2015
Metin Koç, Ibrahim Korpeoglu
Sink mobility is one of the most effective solutions for improving lifetime and has been widely investigated for the last decade. Algorithms for single-sink mobility are not directly applied to the multiple-sink case due to the latter’s specific challenges. Most of the approaches proposed in the literature use mathematical programming techniques to solve the multiple-sink mobility problem. However...... hiện toàn bộ
PKIS: practical keyword index search on cloud datacenter
EURASIP Journal on Wireless Communications and Networking - - 2011
Hyun A. Park, Jae Hyun Park, Dong Hoon Lee
Abstract This paper highlights the importance of the interoperability of the encrypted DB in terms of the characteristics of DB and efficient schemes. Although most prior researches have developed efficient algorithms under the provable security, they do not focus on the interoperability of the encrypted DB. In order to address this lack of practical aspe...... hiện toàn bộ
A spanning tree construction algorithm for industrial wireless sensor networks based on quantum artificial bee colony
EURASIP Journal on Wireless Communications and Networking - Tập 2019 - Trang 1-12 - 2019
Yuanzhen Li, Yang Zhao, Yingyu Zhang
In industrial Internet, many intelligent applications are implemented based on data collection and distribution. Data collection and data distribution in the wireless sensor networks are very important, where the node topology can be described by the spanning tree for obtaining an efficient transmission. Classical algorithms in graph theory such as the Kruskal algorithm or Prim algorithm can only ...... hiện toàn bộ
Relay Techniques for MIMO Wireless Networks with Multiple Source and Destination Pairs
EURASIP Journal on Wireless Communications and Networking - Tập 2006 - Trang 1-9 - 2006
Tetsushi Abe, Hui Shi, Takahiro Asai, Hitoshi Yoshino
A multiple-input multiple-output (MIMO) relay network comprises source, relay, and destination nodes, each of which is equipped with multiple antennas. In a previous work, we proposed a MIMO relay scheme for a relay network with a single source and destination pair in which each of the multiple relay nodes performs QR decompositions of the backward and forward channel matrices in conjunction with ...... hiện toàn bộ
Joint cooperative relay scheme for spectrum-efficient usage and capacity improvement in cognitive radio networks
EURASIP Journal on Wireless Communications and Networking - Tập 2012 - Trang 1-9 - 2012
Qixun Zhang, Zhiyong Feng, Ping Zhang
In order to improve the efficiency of spectrum resource usage and the capacity of wireless networks, cooperative relay techniques which utilize the vacant spectrum of primary users for secondary users' data transmission have been applied in cognitive radio networks. Considering the dynamic time-varying vacant spectrum resources and achievable rate on different channels at relay nodes (RN), the tra...... hiện toàn bộ
Sparse code multiple access on the generalized frequency division multiplexing
EURASIP Journal on Wireless Communications and Networking - Tập 2020 Số 1 - 2020
Guilherme Pedro Aquino, Luciano Leonel Mendes
Abstract Recent advances in the communication systems culminated in a new class of multiple access schemes, named non-orthogonal multiple access (NOMA), where the main goal is to increase the spectrum efficiency by overlapping data from different users in a single time-frequency resource used by the physical layer. NOMA receivers can resolve the inter...... hiện toàn bộ
