  • This paper proposes a novel joint iterative channel estimation and symbol detection algorithm based on MMSE criterion for MIMO-OFDM systems. The performance of the joint iterative algorithm mainly depends on initial channel estimator and iterative algorithm. Therefore, a new channel estimation algorithm is developed based on Time-Frequency Transform(TFT), then the joint iterative channel estimation and symbol detection algorithm according to MMSE criterion by using initial channel estimated values and detected symbols is advanced. Analysis and simulation illustrate that the novel joint iterative algorithm improves remarkably performance both quasi-static and fast time-varying channels.
