This book was released on 2018-03-19 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: DFT modulated filter banks for non-orthogonal multicarrier transmission are considered a strong tool to implement both dynamic spectrum access and spectrum sensing in cognitive radio systems where signaling schemes have to meet different objectives. A constrained optimization approach is presented to design a cognitive radio transceiver which can be tailored to system specifications with a reasonable trade-off between performance and implementation efficiency. In interweave cognitive radio, the secondary user receiver is synchronized in time and frequency by designing a synthesis filter bank preamble with periodic symbols in analogy to short training fields in IEEE 802.11a. A simple post-detection integration at the secondary user receiver is employed for differently coherent detection. In underlay cognitive radio, a novel transmission scheme for secondary user power adaptation is proposed aiming to minimize the secondary user average probability of error for bit-interleaved coded modulation. The powers of the subcarrier signals are adapted subject to total power and stochastic chance-based interference constraints in order to provide a confidence level for limiting the interference at the licensed primary user receiver.

Download or read book Parasitic Antenna Arrays for Wireless MIMO Systems written by Antonis Kalis and published by Springer Science & Business Media. This book was released on 2013-10-11 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book unites two different technologies: parasitic antenna arrays driven via analogue circuits that control the electromagnetic waves generated by the antenna array; and MIMO technology for multi-antenna arrays, typically driven by digital techniques in the baseband domain. The combination of these two technologies has revealed a novel functionality that breaks through the conventional MIMO paradigm, allowing MIMO transmission over the air with the use of antenna arrays that may consist of only a single active element, that is surrounded by a number of passive neighboring antennas. The contributions in the book show the capability of such systems to also perform MIMO transmission. This fact holds the potential of revolutionizing the way small-form wireless terminals operate and seems to set the scene for a win-win situation, achieving MIMO transmission with very small and cheap antenna arrays. The book is structured to provide a well-rounded treatment of the various facets of this newly discovered wireless communication capability. All relevant technical angles, ranging from information theoretic to electromagnetic considerations; from analogue circuit to digital baseband control for signal generation; and from channel modeling to communication theoretic aspects are taken into account. A good balance between theory, practical considerations and over-the-air experimentation is proposed and reflected in the chapter outline. Finally, a discussion and early evidence related to potential applications as well as the relevance to current and upcoming wireless standards is provided.
