In the last decade the technique of multi-carrier spread-spectrum (MC-SS) for
wireless broadband multimedia applications has been receiving wide interests [ 1].
Since 1993 various combinations of the multi-carrier (MC) modulation and the spread
spectrum (SS) technique have been introduced. Today, the field of MC-SS
communications is considered to be an independent and important research topic with
increasing activities. Several deep system analysis and comparisons of Multi-Carrier
CDMA and Multi-Carrier DS-CDMA with DS-CDMA have been performed that
show the superiority of MC-SS systems. New application fields have been proposed
such as high rate cellular mobile (4G), high rate wireless indoor and fixed wireless
access (FW A). In addition to system level analysis, a multitude of research activities
has been addressed to develop appropriate strategies on detection, interference
cancellation, channel coding, modulation, synchronization and low cost
implementation design.
Offering a trade-off between coverage, data rate and mobility with a generic air
interface architecture will be the primary goal of the next generation wireless systems.
Users having no mobility and the lowest coverage distance (pico cells) with an ideal
channel condition shall be able to receive the highest data rate, where on the other
hand the subscriber with the highest mobility conditions and highest coverage area
(macro cells) shall be able to receive the necessary data rate to establish the required
communication link. Besides the introduction of new technologies to cover the need
of higher data rates and new services, the integration of the existing technologies in a
common platform as it is illustrated in Figure-1 will be an important objective of the
next generation wireless systems beyond 3G.
In other words, the design of a generic multiple access scheme for the incoming
4G wireless systems will be challenging. This new multiple access scheme shall
