Abstract-- Wireless systems often implement one or more types
of diversity in order to achieve reliable communication. Different
types of diversity techniques such as temporal, frequency, code,
and spatial have been developed in the literature. In addition to
the destructive multipath nature of wireless channels, frequency
selective channels pose intersymbol interference (ISI) while
offering frequency diversity for successfully designed systems.
Orthogonal frequency division multiplexing (OFDM) has been
shown to combat ISI extremely well by converting the frequency
selective channel into parallel flat fading channels. On the other
hand, bit interleaved coded modulation (BICM) was shown
