The benefits and success of multi-carrier (MC) modulation on one
side and the flexibility offered by the spread spectrum (SS)
technique on the other side have motivated many researchers to
investigate the combination of both techniques since 1993. This
combination known as multi-carrier spread spectrum (MC-SS) benefits
from the advantages of both systems and offers high flexibility,
high spectral efficiency, simple detection strategies, narrow-band
interference rejection capability, etc. The basic principle of this
combination is straightforward: The spreading is performed as
direct sequence spread spectrum (DS-SS) but instead of transmitting
the chips over a single carrier, several sub-carriers are employed.
The MC modulation and demodulation can easily be realized in the
digital domain by performing IFFT and FFT operations. The
separation of the users' signals can be performed in the code
domain. MC-SS systems can perform the spreading in frequency
direction, which allows for simple signal detection strategies.
Since 1993, MC-SS has been deeply studied and new alternative
solutions have been proposed. Meanwhile, deep system analysis and
comparison with DS-CDMA have been performed that show the
superiority of MC-CDMA. The aim of this book is to edit the
ensemble of the newest contributions and research results in this
new field that have been presented during the 4th International
Workshop on Multi-Carrier Spread-Spectrum (MC-SS 2003), held in
Oberpfaffenhofen, Germany.
