Diversity Combining and Equalization with TCM for Wireless CommunicationsWireless 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 ReductionWireless 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 UserWireless 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

Reliability and Mobility Load Balancing in Next Generation Self-organized Networks: Using Stochastic Learning AutomataWireless 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

Load Balanced Congestion Adaptive Routing for Randomly Distributed Mobile Adhoc NetworksWireless 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
