| Abstract: | Accurate channel state information (CSI) is required at the receiver in a space-time coded OFDM system. In thispaper, several channel estimation methods for space-time coded OFDM systems are studied. A detailed analysis andcomparison are made in terms of mean-squared error, complexity, tracking rate and frequency efficiency. Finally theirperformance is verified via MATLAB simulations. |
