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 de-veloped 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
