Download or read book Radio Resource Management in Cellular Systems written by Nishith D. Tripathi and published by Springer Science & Business Media. This book was released on 2006-04-18 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radio Resource Management in Cellular Systems is the first book to address the critical issue of radio resource management in emerging (i.e., third generation and beyond) wireless systems. This book presents novel approaches for the design of high performance handoff algorithms that exploit attractive features of several existing algorithms, provide adaptation to dynamic cellular environment, and allow systematic tradeoffs among different system characteristics. Efficient handoff algorithms cost-effectively enhance the capacity and quality of service (QoS) of cellular systems. A comprehensive foundation of handoff and related issues of cellular communications is given. Tutorial-type material on the general features of 3G and 3.5G wireless systems (including CDMA2000, UMTS, and 1xEV-DO) is provided. Key elements for the development of simulators to study handoff and overall RF performance of the integrated voice and data cellular systems (including those based on CDMA) are also described. Finally, the powerful design tools of neural networks and fuzzy logic are applied to wireless communications, so that the generic algorithm approaches proposed in the book can be applied to many other design and development areas. The simulation models described in the book represent a single source that provides information for the performance evaluation of systems from handoff and resource management perspectives. Radio Resource Management in Cellular Systems will prove a valuable resource for system designers and practicing engineers working on design and development of third generation (and beyond) wireless systems. It may also be used as a text for advanced-level courses in wireless communications and neural networks.

Download or read book Radio Resource Management in Advanced OFDMA based Cellular Networks written by Rajarajan Sivaraj and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent advancements in radio access technologies for 4G+/5G next-generation telecommunication networks are based on the following principles: (i) Bandwidth aggregation, (ii) Network Heterogeneity, (iii) Transmit Diversity and (iv) Spatial Multiplexing. 3GPP Release 10+ specification suites have standardized techniques based on the aforementioned principles for LTE-Advanced systems as part of 4G+/5G deployments.Some of these techniques in LTE-Advanced deployments include carrier aggregation, evolved Multimedia Broadcast/Multicast Services (eMBMS) over LTE Single frequency networks, enhanced Inter-Cell Interference Coordination (eICIC) in LTE heterogeneous (HetNets), Coordinated Multi-point transmission (CoMP) with MIMO OFDMA 2D/3D beamforming for multi-cell self-organized networks (SoN), LTE deployments in unlicensed bands and their co-existence with WiFi, etc. Carrier Aggregation is based on aggregate frequency sub-band carriers of the same/varying bandwidths in the cellular base stations from the licensed band exclusively meant for cellular deployment (like LTE-Advanced Carrier Aggregation), as well as from the unlicensed band where other radio access technologies are also deployed (like License-Assisted Access and LTE-WiFi Aggregation in Unlicensed LTE). LTE-WiFi aggregation, in addition to eICIC HetNets, is also based on network heterogeneity. Network Heterogeneity deals with co-existence of cellular base stations with heterogeneous transmission capabilities or different radio access mechanisms. In HetNets, small cell deployments are used to enhance the coverage and capacity of macro cells. However, since LTE small cells with lower transmission power transmits on the same frequency bands as the macro cells (with higher transmission power), the latter heavily interferes with the former. eICIC focuses on co-existence of LTE small cells with LTE macro cells by appropriately managing their co-channel interference. Video broadcast over LTE single frequency networks is based on transmit diversity, which coordinates multiple LTE base stations to synchronize their redundant data transmissions on the same frequency-time resources and using the same modulation rates across the base stations, which increases the SINR at the users due to constructive combining of signals. CoMP with coordinated beamforming techniques is based on spatial multiplexing, which deals with transmission of independently-encoded data signals on the same frequency-time resources across multiple antennae deployed on the cellular base stations by overcoming interference. Our dissertation broadly discusses spectrum allocation and channel quality issues concerning the above deployments, and provides radio resource management and self-organized network solutions with regards to optimizing pertinent system utility functions. Particularly, our dissertation focuses on a common goal of analyzing the impact of cell-edge users in these network deployments and improving their overall performance, especially in terms of throughput and fairness. Furthermore, our dissertation focuses on meeting the Quality-of-Service (QoS) requirements of the operator in terms of delivering guaranteed bit rates for the subscribed applications, and enhancing the overall Quality-of-Experience (QoE) of users.

Available in PDF, EPUB and Kindle. Book excerpt: The IFIP TC-6 9th International Conference on Personal Wireless Communi- tions, PWC 2004 is the main conference of the IFIP Working Group 6. 8, Mobile and Wireless Communications. The ?eld of personal wireless communications is steadily growing in imp- tance,fromanacademic,industrialandsocietalpointofview. Thedroppingcost of WLAN and short-range technologies such as Bluetooth and Zigbee is causing the proliferation of personal devices and appliances equipped with radio int- faces. Together with the gradual deployment of powerful wireless infrastructure networks, such as 3G cellular systems and WLAN hotspots, the conditions are being created for a?ordable ubiquitous communication involving virtually any artifact. This enables new application areas such as ambient intelligence where a world of devices, sensors and actuators surrounding us use wireless technology to create systems that assist us in an unobtrusive way. It also allows the - velopment of personal and personalized environments that accompany a person whereverheorshegoes. ExamplesarePersonalAreaNetworks(PAN)physically surrounding a person, and personal networks with a potentially global reach. PWC 2004 re?ects these developments, which are happening on a global scale. Researchers from all over the world, and in particular a large number from Asia, made contributions to the conference. There were 100 submissions. After a thorough reviewing process, 25 full papers and 13 short papers were retained for presentation in the technical sessions. The papers cover the whole range of wireless and mobile technologies: cellular systems, WLAN, ad hoc and sensor networks, host and network mobility, transport protocols for wireless systems, and the physical layer.
