In mobile reception, the reliability of orthogonal frequency division multiplexing (OFDM) is
limited because of the time-varying nature of the channel. This causes intercarrier …

In mobile radio communication, the fading channels generally exhibit both time-selectivity
and frequency-selectivity. Orthogonal frequency-division multiplexing has been proposed to …

In this paper, we consider the case of a high-speed mobile receiver operating in an
orthogonal frequency-division multiplexing (OFDM) communication system. We present an …

Channel variation during an OFDM block leads to the loss of orthogonality among
subcarriers, resulting in inter-carrier interference (ICI) in orthogonal frequency division …
