- Abstract
- The capacity region of multiple-input multipleoutput (MIMO) broadcast channel (BC) has attracted considerable attention recently. The greedy block MMSE QR decomposition with dirty paper coding (greedy block MMSE-DP) scheme is a solution to achieves extremely close to channel capacity with limited feedback of channel state information at transmitter (CSIT). In this paper, we analysis the performance and consider the reconfigurable implementation of greedy block MMSE-DP. Numerical results indicate that the greedy block MMSE-DP approach significantly outperforms the TDMA-MIMO approach in terms of the system throughput even when a large amount of quantization error is added to the feedback information (e.g., when signal-to-quantization-error ratio (SER) values are 14, 10, and 6 dB). The scheme is shown to be appropriate for reconfigurable implementation. © 2005 IEEE.
