Abstract
OFDM (Orthogonal Frequency Division Multiplexing) scheme is robust to frequency selective fading in wireless channels, because it is insensitive to multipath delay spread within guard interval. However, no one knows, when a frequency selective fading channel is given, in which case OFDM scheme can achieve better BER (bit error rate) performance, the frequency selective fading channel or a frequency selectivity-removed (frequency non-selective) fading channel if we can remove the frequency selectivity from the channel.
In this paper, assuming four kinds of weight control methods in adaptive antenna array, such as all signal combining and one signal selection within guard interval, we discuss whether OFDM really prefers frequency selective fading channels.
