Opis

Since the principle of multi-carrier code division multiple access (MC-CDMA) was simultaneously proposed by Khaled Fazel et al. and Nathan Yee et al. at the IEEE International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC) in the year 1993, multi-carrier spread spectrum (MC-SS) has rapidly become one of the most wide spread independent research topics on the field of mobile radio communications. Therefore, the International Workshop on Multi-Carrier Spread Spectrum (MC-SS) was initiated in the year 1997. Multi-carrier and spread spectrum systems with their generic air interface and adaptive technologies are considered as potential candidates to fulfill the requirements of next generation mobile communications systems. The material summarized in this volume was selected for the 6th International Workshop on Multi-Carrier Spread Spectrum (MC-SS 2007) held in Herrsching, Germany from 07-09 May 2007. The workshop was organized by the Institute of Communications and Navigation of the German Aerospace Center (DLR) in Oberpfaffenhofen, Germany. During the workshop, many hot topics in the field of MC-SS were covered. First, several presentations regarding General Issues were given. Iterative Decoding strategies were also discussed. Furthermore, a special session was addressed on Interleave Multiple Division Access (IDMA). In the areas of Spectrum and Interference, Data Transmission, Adaptive Transmission, Multiple Antennas, Multi-Cell and Multi-Link, and Synchronization and Tracking new and innovative algorithms, strategies, and systems were proposed. Finally, a dominant hot topic during this workshop was the problem of Channel Estimation.

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 capabilities, 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 Multi-Carrier Spread Spectrum 2007 is to edit the ensemble of the newest contributions and research results in this new field that have been presented during the 6th International Workshop on Multi-Carrier Spread Spectrum (MC-SS 2007), held in Herrsching, Germany.
