An Iterative Joint Channel Estimation and Symbol Detection Algorithm Based on Prediction for OFDM Systems
基于预测的OFDM系统迭代联合信道估计与符号检测算法

In this paper, an iterative joint channel-estimation and symbol-detection algorithm based on prediction is presented for orthogonal frequency-division multiplexing systems. Considering the correlation between impulse responses, the prediction method is introduced into the iterative channel estimation. The initial channel value of iterative estimation is predicted in each symbol. Several prediction methods are simulated and compared. The simulation results show that contrasted to the conventional scheme the proposed algorithm improves the convergence capability and system performance dramatically.
