In this paper, we combine the idea of high rate space-time codes with the cooperative MIMO wireless networks to reduce the overall delay incurred in relaying signals to more than one receiver. The relay structure is optimized in order to achieve maximum SNR at the receiver nodes. This combination provides a significant reduction in the delay required for the relaying and transmission of the signals to the multiple receivers with a minute loss in performance. We have also shown that this loss in the performance could be recovered by selecting more number of relays. We propose three different relaying strategies for high rate space-time codes, which are very useful in providing faster handoffs for wireless networks.
