| Abstract: | The space-time block code （STBC） is discussed in this paper. Taking Alamouti transmit diversity scheme as an example, the theory of STBC was expatiated and the STBC of Alamouti was introduced to the IEEE802.16d-OFDM PHY layer and simulated. The results show that the performance of system is enhanced by the combination of space-time block coding and orthogonal frequency division multiplexing （OFDM）. |
