Offers comprehensive insight into the theory, models, and techniques of ultra-dense networks and applications in 5G and other emerging wireless networks The need for speed--and power--in wireless communications is growing exponentially. Data rates are projected to increase by a factor of ten every five years--and with the emerging Internet of Things (IoT) predicted to wirelessly connect trillions of devices across the globe, future mobile networks (5G) will grind to a halt unless more capacity is created. This book presents new research related to the theory and practice of all aspects of ultra-dense networks, covering recent advances in ultra-dense networks for 5G networks and beyond, including cognitive radio networks, massive multiple-input multiple-output (MIMO), device-to-device (D2D) communications, millimeter-wave communications, and energy harvesting communications. Clear and concise throughout, Ultra-Dense Networks for 5G and Beyond - Modelling, Analysis, and Applications offers a comprehensive coverage on such topics as network optimization; mobility, handoff control, and interference management; and load balancing schemes and energy saving techniques. It delves into the backhaul traffic aspects in ultra-dense networks and studies transceiver hardware impairments and power consumption models in ultra-dense networks. The book also examines new IoT, smart-grid, and smart-city applications, as well as novel modulation, coding, and waveform designs. One of the first books to focus solely on ultra-dense networks for 5G in a complete presentation Covers advanced architectures, self-organizing protocols, resource allocation, user-base station association, synchronization, and signaling Examines the current state of cell-free massive MIMO, distributed massive MIMO, and heterogeneous small cell architectures Offers network measurements, implementations, and demos Looks at wireless caching techniques, physical layer security, cognitive radio, energy harvesting, and D2D communications in ultra-dense networks Ultra-Dense Networks for 5G and Beyond - Modelling, Analysis, and Applications is an ideal reference for those who want to design high-speed, high-capacity communications in advanced networks, and will appeal to postgraduate students, researchers, and engineers in the field.
This book presents several contributions to improve the overall performance of the cooperative communication in the decentralized networks. It emphasizes on the development of the new relay selection protocol for enhancing the outage probability and spectral efficiency of the cooperative communication. The book also studied the effect of cooperative communication on the throughput and delay. Finally, the book considered power allocation problem of the source and relay to maintain the bit error rate of cooperative communication.

Cognitive radio is an exciting emerging technology that has the ability to deal with the requirements of the frequency spectrum. CR allows usage of the frequency spectrum more efficiently. CR systems built in this book based on SDR to distinguish between signal and noise. The heavily used generated modulated signals: FSK, PSK and QAM are generated and used in this work. These systems consist of feature extraction and decision stages. Both instantaneous features and statistical features are used in this work. Neural networks are also used in the detection process. Six detection systems are proposed in this work. Most of these systems are based on CFAR The assessment of results showed that the proposed CR detection systems provide detection probability higher than the other proposed systems of the published papers. A novel technique is presented to estimate SNR for CR based on statistical features by calculation the cumulants for signals. This is an indirect method for SNR measurements. Thresholds decision and NVG-RAM detectors at intermediate frequency of 20MHz which are based on statistical features are implemented by FPGA Spartan-3A DSP 3400A due to their higher performance.
