In this paper, two channel estimation schemes for OFDM systems are investigated in a time-variant channel. The orthogonality of the subcarriers is destroyed in a time-variant chann...
In this paper, we propose a novel channel estimation technique based on 2D spread pilots. The merits of this technique are its simplicity, its flexibility regarding the transmissi...
— We propose an improved channel estimator for reuse-1 orthogonal frequency division multiplexing (OFDM) cellular systems1 . The proposed channel estimation technique exploits de...
