In this paper, we investigate several efficient interpolation techniques for pilot symbol
assisted channel estimation in OFDM. The interpolation methods studied include two …

Linear minimum mean square error (LMMSE) is by definition the optimal channel estimator
in the sense of mean square error criterion, but its practical application is limited by its high …

In this paper we provide a general framework for the performance analysis o pilot-aided
linear channel estimators class including the general interpolation, least squares (LS) …

In this study, the performance of different preamble‐based channel estimation techniques is
analysed for orthogonal frequency division multiplexing/offset quadrature amplitude …

In this paper, we investigate pilot symbol assisted channel estimation in OFDM system. To
obtain the consistent estimation of communication channel, it is necessary to perform …

In this paper, we derive a closed-form expression for the Bit Error Probability (BEP) of an
