Opis

Multi-antenna techniques are widely considered to be the most promising avenue for significantly increasing the bandwidth efficiency of wireless data transmission systems. In so called MIMO (multiple input multiple output) systems, multiple antennas are deployed both at the transmitter and the receiver. In MISO (multiple input single output) systems, the receiver has only one antenna, and the multiple transmit antennas are used for transmit diversity.

The key aspects of multiple antenna transceiver techniques for evolving 3G systems and beyond are presented. MIMO and MISO (transmit diversity) techniques are explained in a common setting. In particular, the book covers linear processing transmit diversity methods with and without side information at the transmitter (feedback), including the current transmit diversity concepts in the WCDMA standards, as well as promising MIMO concepts, crucial for future high data rate systems.
As an example, MIMO and MISO aspects of 3GPP HSDPA (high speed downlink packet access) will be considered. Furthermore, examples of high throughput, low complexity space-time codes will be provided, when signalling without side information (open loop concepts). The theory of linear space-time block codes will be developed, and optimal non-orthogonal high throughput codes will be constructed, both for MIMO and MISO systems. Performance may be further improved by feedback from receiver to transmitter. The corresponding closed loop modes in the current 3GPP specifications will be discussed, along with their extensions for more than two transmit antennas. In addition, feedback signalling for MIMO channels will be addressed. Optimal quantisation methods of the feedback messages will be discussed. Finally, hybrid schemes are constructed, where the amount of feedback is reduced using partly open, partly closed loop signalling.
* Provides a concise and up-to-date description of perhaps the most active area of research in wireless communications
* Unique in presenting recent developments in both WCDMA and MIMO
* MIMO and MISO techniques are explained in a common setting
* Special emphasis is placed on combining theoretical understanding with engineering applicability
For Research engineers in academia and industry, and development engineers in 3G system design as well as research students.

Multi–antenna techniques are currently an extremely active area of research in wireless communications. They are widely considered to be the most promising avenue for significantly increasing the bandwidth efficiency of wireless data transmission systems and this exceptional volume presents their key aspects. MIMO and MISO (transmit diversity) techniques are explained in a common setting, in a clear and concise manner, and special emphasis is placed on combining theoretical understanding with engineering applicability. Practical examples include the transmit diversity concepts in the WCDMA standard, as well as several promising novel MIMO concepts, crucial for future high data rate systems. Such techniques are currently being considered in relevant standardization bodies (e.g. 3GPP, 3GPP2) and they are likely to form the basis for bandwidth efficient communication for systems beyond 3G.

• Covers the theory and applications of linear processing transmit diversity and MIMO methods that operate both with and without channel state information
• Presents specific examples of high throughput, low complexity space–time codes both for MIMO and MISO systems
• Provides a detailed and elaborated discussion on the theory of linear space–time block codes
• Contains closed loop transceiver techniques for maximal exploitation of channel state feedback

If you need to understand why multi–antenna techniques are important when increasing the capacity/data rates for future wireless systems then you should read this book. Multi–antenna Transceiver Techniques for 3G and Beyond will have instant appeal to research engineers in academia and industry, development engineers in 3G system design, research students and managers.
