Employing multiple transmit and receive antennas, namely using multi-input multi-output (MIMO) systems, has proven to be a major breakthrough in providing reliable wireless communication links. Since their invention in the mid-1990s, transmit diversity, achieved through space-time coding, and spatial multiplexing schemes have been the focus of much RESEARCH in the area of wireless communications.

The aim of this book, the first of two volumes, is to present selected RESEARCH that has been undertaken under COST Action IC0902 ‘‘Cognitive Radio and Net- working for Cooperative Coexistence of Heterogeneous Wireless Networks’’ (http://newyork.ing.uniroma1.it/IC0902/). COST (European Cooperation in Sci- ence and Technology) is one of the longest-running European frameworks sup- porting cooperation among scientists and RESEARCHers across Europe.

The idea of writing this book entitled “Cognitive Networked Sensing and Big Data” started with the plan to write a briefing book on wireless distributed computing and cognitive sensing. During our RESEARCH on large-scale cognitive radio network (and its experimental testbed), we realized that big data played a central role. As a result, the book project reflects this paradigm shift. In the context, sensing roughly is equivalent to “measurement.”

The book you’re holding, physically or electronically, is the result of a very interesting, challenging but also rewarding RESEARCH project. The RESEARCH was carried out in different contexts and cooperations but it was centered around the following question: how can we make the RF transmitters of our modern com- munication systems (WiFi, GSM, LTE, and so on) more flexible and more efficient at the same time.

This book presents, in a unitary and novel perspective, some of the RESEARCH work the authors have carried out over the last decade, along with several collaborators and students. The roots of this book can be traced back to the design of adaptive sequence detection algorithms for channels with parametric uncertainty. The explosion of turbo codes and iterative decoding around the middle of the Nineties has motivated the design of iterative (turbo and graph-based) detection algorithms.

When joining Siemens in 2001, I also extended my RESEARCH interest towards radio net- work planning methodologies. This area of RESEARCH brought together my personal interest in mobile communications and in the design of efficient algorithms and data structures. Between 2001 and 2003, I participated in the EU project Momentum, which was target- ing the performance evaluation and optimization of UMTS radio networks. I

With the advancement of technology and miniaturization of electronic devices, applications of wireless sensor networks (WSNs) can be seen in diverse areas in our lives. In fact, these WSNs have gained a lot of attention from both the RESEARCH community and industry, making them easily available on the market. An extensive amount of RESEARCH, easy availability, and cheap cost make them useful in various types of futuristic applications as well.

During the past two decades there has been a substantial growth in RESEARCH in wireless communications. The number of journals published from various parts of the world catering to the RESEARCH community has grown exponentially. Despite such a growth, the engineering community still needs more information so as to thoroughly comprehend wireless channel characteristics. What specifically must be understood are the effects of channel degradation brought on by statistical fluctua- tions in the channel.

The writing of this book was prompted by two main developments in wireless communications in the past decade. First is the huge surge of RESEARCH activities in physical-layer wireless communication theory. While this has been a subject of study since the 60’s, recent developments in the field, such as opportunistic and multi-input multi-output (MIMO) communication techniques, have brought completely new per- spectives on how to communicate over wireless channels.
