Further Information

The PSAM (Pilot-Symbol Assisted Modulation) technique is the common channel estimation method for OFDM systems by using the time and frequency correlation of (lie channel. ESAE (Extended Symbol Aided Estimation) method has more robust feature in fast fading channel. But ESAE has an unstable property in a high-speed environment. In this paper, we proposed the Turbo ESAE and Adaptive Turbo ESAE channel estimation algorithm that is based on conventional ESAE algorithm and utilize the soft output of the Turbo decoder. Computer simulation results show that the proposed methods have lower algorithm complexity and shorter processing delay than iterative channel estimation algorithms. and can decrease the effects of the error accumulation in time and frequency selective channel.
