... derives a basic and simplified approach to MMSE batch channel estimation for OFDM systems. To show its efficiency, the performance bounds are analyzed and the performance degradation due to a mismatch ... actual channel statistics and SNR may vary within OFDM block, we have also analyzed the effect of modelling mismatch on the estimator performance and shown both analyticall...
