摘要：
When the Alamouti code is applied (as a space-time block code) to an OFDM system with transmit diversity, the simple Alamouti decoding requires that each subchannel is flat-fading and constant over two symbol periods(Alamouti code-word period). The second requirement makes the Alamouti decoding scheme not suitable for time varying channels. In this paper, we propose a new decision directed receiver to better accommodate time varying channels.
