1. Base Station Coordination in Multicell MIMO Networks
Sammanfattning : The use of multi-antenna technology, also referred to as multiple-input multipleoutput (MIMO), has been shown to improve both the achievable data rates and the link reliability in single-cell wireless systems without a need for extra power or bandwidth. The promised gains of MIMO techniques are, however, severely degraded in a multicell environment due to the presence of intercell interference,especially for users at the cell edge. LÄS MER
2. Scheduling and Base-Station Cooperation in MIMO Downlink Systems
Sammanfattning : Multiple input multiple output (MIMO) techniques have been shown to improvethe capacity and link reliability of wireless communication without a need to extrapower and bandwidth. In multi-user (MU) MIMO networks, a linear increaseof sum capacity in the number of transmit antennas can be achieved by usinglinear precoding combined with efficient scheduling algorithms. LÄS MER
