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.

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. aeo Provides a concise and up--to--date description of perhaps the most active area of research in wireless communications aeo Unique in presenting recent developments in both WCDMA and MIMO aeo MIMO and MISO techniques are explained in a common setting aeo 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.
