To operate future generation multimedia communications systems high
data rate transmission needs to be guaranteed with a high quality
of service. For instance, the third generation cellular mobile
systems should offer a high data rate up to 2 Mbit/s for video,
audio, speech and data transmission. The important challenge for
these cellular systems will be the choice of an appropriate
multiple access scheme. The advantages of the spread spectrum
technique are: High immunity against multipath distortion, no need
for frequency planning, high flexibility and easier variable rate
transmission etc. On the other hand, the technique of multi-carrier
transmission has recently been receiving wide interest for high
data rate applications. The advantages of multi-carrier
transmission are the robustness in the case of frequency selective
fading channels, in particular the reduced signal processing
complexity by equalization in the frequency domain, and in the
capability of narrow-band interference rejection.The advantages and
success of multi-carrier (MC) modulation and the spread spectrum
(SS) technique has led to the combination of MCM with SS, known as
multi-carrier spread-spectrum (MC-SS) for cellular systems. This
combination, benefits from the advantages of both schemes: Higher
flexibility, higher spectral efficiency, simpler detection
techniques, narrow band interference rejection capability, etc.
Multicarrier-Spread-Spectrum comprises a collection of papers which
collectively provide a state-of-the-art overview of this emerging
multiple access scheme. It will be a valuable reference for all
researchers and practitioners working on the area of wireless
communications and networking.
