Book excerpt: Performance evaluation studies constitute a considerable portion of the wireless communications literature. The importance of these studies stems from the fact that theyprovide system designers with feedback on the quality of their designs and hence, anopportunity for enhancements before actual deployment.This book represents a comprehensive study on the performance of mobile radio networks. It is divided into two main parts where in each part adifferent perspective is adopted: a system-level perspective is considered in the firstand a link-level one in the second. In the first part, the TDD mode of operation of WCDMA technology is thoroughly investigated under different scenarios and a complete framework forperformance evaluation is proposed. In the second part, a number of problems related to the performance of communicationsystems over the Weibull fading channel are addressed. In particular, the performance of different diversity schemes is extensively studied under different scenarios involving theexistence/non-existence of cochannel interference. Throughout this work, Monte Carlo simulations are provided to complement theanalytical results presented.

This book was released on 2001-06-30 with total page 243 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.

This book was released on 2014 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation addresses the performance evaluation of radio resource management (RRM) for 3GPP LTE OFDMA Cellular data networks. The radio resource allocation strategies address processes in which the available scarce and prohibitively expensive radio resources are assigned to each active user. An efficient scheduling algorithm plays an important role for effective utilization of radio resources, high spectrum efficiency, low latency, and fairness among users whithin a system as well as for the entire system performance. The reseach work presented in this dissertation focuses on the performance evaluation of the common packet scheduling algorithms, namely Maximum Rate (MR), Round Robin (RR), and Proportional Fair (PF). Only the scheduling for the downlink (DL) transmission of the LTE cellular systems is considered. The performance evaluation is performed for a regular hexagonal multi cell deployment, universal frequency reuse scheme, Single Input Single Outpt(SISO) versus spatial multiplexing (SM) Multiple Input Multiple Output (MIMO) omnidirectional antenna confugrations, various bandwidth sizes, Adaptive Modulation and Coding (AMC) technique, and multipath selective fading channel conditions through Monte Carlo type simulations. The design of the custom built system level simulator, implementation of various scenarios of the LTE system, and the simulator findings are thoroughly described in the document. The simulator presents an universal framework for performance evaluation of existing and for development of new scheduling algorithms.
