摘要：

By exploiting the wireless MIMO (multiple input multiple output) channel structure, a brand new space-time code design criterion is derived. Based on the new criterion, we propose two low-complexity channel-adapted space-time (CAST) coding schemes, where trade-offs among codeword error rate, data throughput and computational complexity are very flexible. Simulation results confirm that, in the frequency-selective MIMO channels, the CAST coding schemes can perform significantly better than the existing space-time codes, e.g., Alamouti space-time orthogonal code.
