Diversity Combining and Equalization with TCM for Wireless Communications
Wireless Personal Communications - Tập 20 - Trang 41-60 - 2002
Yue Chen, K.B. Letaief, Justin C.-I. Chuang
This paper presents an equalization structure in which antennadiversity, adaptive decision feedback equalization (DFE), interleavingand trellis-coded modulation (TCM) can be effectively combined to combatboth ISI and cochannel interference in cellular mobile radioenvironments. The feedback filter of the DFE can use either tentative orfinal decision symbols of the TCM Viterbi decoding to cancel tai...... hiện toàn bộ
Tapered Antenna Array with Non-identical Triangular MSA Elements for FSLL Reduction
Wireless Personal Communications - Tập 106 - Trang 1339-1352 - 2019
Bharti Singh, Nisha Sarwade, K. P. Ray, Amit A. Deshmukh
Reduced interference from nearby communication systems is an essential need in all generations of wireless communication systems. In this paper, interference is reduced by reducing the first side lobe level (FSLL) by using the concept of tapering realized with non-identical triangular elements. Resonance frequency of an Equilateral triangular microstrip antenna depends on its patch height. This pr...... hiện toàn bộ
Cognitive Mesh Network Under Interference from Primary User
Wireless Personal Communications - Tập 45 - Trang 385-401 - 2008
Rocco Di Taranto, Hiroyuki Yomo, Petar Popovski, Kentaro Nishimori, Ramjee Prasad
In a commonly accepted usage scenario, a cognitive radio appears as a secondary user of certain spectrum which is licensed to another, primary system. A prominent example of cognitive system is a mesh network operating under the interference from primary system. For such a scenario, we propose techniques for efficient secondary usage of spectrum, which rely on the adaptive array antenna in order t...... hiện toàn bộ

Available Bandwidth Estimation Using Collision Probability, Idle Period Synchronization and Random Waiting Time in MANETs: Cognitive Agent Based Approach
Wireless Personal Communications - Tập 85 - Trang 597-621 - 2015
Shilpa Shashikant Chaudhari, Rajashekhar C. Biradar
In Mobile Ad hoc NETworks (MANETs), each node estimates available bandwidth (AB) before transmission of real-time multimedia data, as the channel is shared. The existing AB estimation techniques lack accuracy and add overhead. Accuracy of these AB estimation techniques could be enhanced by adopting some intelligent techniques. Intelligent software agents such as cognitive agent (CA) have significa...... hiện toàn bộ
Reliability and Mobility Load Balancing in Next Generation Self-organized Networks: Using Stochastic Learning Automata
Wireless Personal Communications - Tập 114 - Trang 2389-2415 - 2020
Amin Mohajer, Maryam Bavaghar, Hamid Farrokhi
Self-organizing networking (SON) is an automation technology designed to make the planning, configuration, management, optimization and healing of mobile radio access networks simpler and faster. Most current self-organization networking functions apply rule-based recommended systems to control network resources which seem too complicated and time-consuming to design in practical conditions. This ...... hiện toàn bộ

Devesh Shukla, Arun Prakash, Rajeev Tripathi
With the advancements and increase in the transportation system in the current scenario, making transports intelligent is an important aspect for enhancing the safety, security and related commercial applications. Vehicular ad-hoc network has been evolved for the implementation of intelligent transportation systems. Vehicular scenario comprising of multipath fading, interference, dispersion and mo...... hiện toàn bộ
Load Balanced Congestion Adaptive Routing for Randomly Distributed Mobile Adhoc Networks
Wireless Personal Communications - Tập 77 - Trang 2723-2733 - 2014
Geetam Singh Tomar, Laxmi Shrivastava, Sarita Singh Bhadauria
In mobile ad hoc networks, congestion occurs due to limited sources of the network, which leads to packet losses, bandwidth degradation and wastes time and energy on congestion recovery. Various techniques have been developed in attempt to minimize congestion in uniformly distributed networks. In this paper, a load balanced congestion adaptive routing algorithm has been proposed for randomly distr...... hiện toàn bộ
