Abstract：In the paper, assuming frequency-selective channel, a recursive semi-blind joint equalization and decoding method for Alamouti space-time block code is proposed. Based on subspace-based blind equalization method, the proposed method sequentially decodes Alamouti space-time block code without channel state information by exploiting the structure of the space-time block code and a few pilot symbols. In contrast with previous block-based blind decoding methods, the proposed method is more amicable to allowing tradeoff between performance and complexity. Simulation results demonstrate the effectiveness and flexibility of the proposed method.
