Abstract: In the recent time, there have been investigation efforts into time domain channel estimation techniques, exploiting underlying sparseness in OFDM channel, for multiuser-based orthogonal frequency division multiplexing-interleave division multiple access (OFDM-IDMA) systems. This paper developed… read more here.

Abstract: Since the channel estimation performance is directly affected by the pilot positions, it has been a major task in multicarrier transmission schemes to adjust the pattern of pilot distribution for the purpose of minimizing the… read more here.
