摘要：
A novel joint iterative channel estimation and space-frequency decoding algorithm was proposed for SFBC-OFDM systems. At first, a new channel estimation algorithm based on time-frequency transforms (TFT) was developed to improve the performance of the initial channel estimator, and then, by exploiting the channel estimated values and the decoded symbols, the joint iterative channel estimation and space-frequency decoding algorithm was advanced. Analyses and simulation results show that the novel joint iterative algorithm improves performance remarkably for the quasi-static, fast time-varying and correlated channels.
