Multi-Carrier Spread-Spectrum has been deeply studied and new alternative solutions have been proposed. This book edits the newest contributions and research results in this new field presented at the Third International Workshop on MC-SS & Related Topics, held in Oberpfaffenhofen, Germany.
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.
Khaled Fazel Stefan Kaiser Digital Microwave Systems German Aerospace Center (DLR) Bosch Telecom GmbH Institute for Communications Technology D-71522 Backnang, Germany D-82234 Wessling, Germany In this last decade of this millennium the technique of multi-carrier transmission for wireless broadband multimedia applications has been receiving wide interests. Its first great success was in 1990 as it was selected in the European Digital Audio Broadcasting (DAB) standard. Its further prominent successes were in 1995 and 1998 as it was selected as modulation scheme in the European Digital Video Broadcasting (DVB-T) and in three broadband wireless indoor standards, namely ETSI-Hiperlan-II, American IEEE-802. 11 and Japanese MMAC, respectively. The benefits and success of multi-carrier (MC) modulation in one side and the flexibility offered by spread spectrum (SS) technique in other hand motivated many researchers to investigate the combination of both techniques, known as multi-carrier spread-spectrum (MC-SS). This combination benefits from the main 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 SS (DS-SS) but instead of transmitting the chips over a single sequence carrier, several sub-carriers could be employed. As depicted in Figure 1, after spreading with assigned user specific code of processing gain G the frequency mapping and multi-carrier modulation is applied. In the receiver side after multi-carrier demodulation and frequency de-mapping, the corresponding detection algorithm will be performed."
Men with assault rifles, balaclavas and Hawaiian shirts pulled over bulletproof vests. Horned warriors with painted faces and fur headdresses draped over their naked torsos. The storming of the Capitol brought together men who had previously come across one another only online in the Manosphere. These were men with a common interest, followers of a male-supremacist ideology, who rioted in order to fight for their privilege. Before then, the world had looked on as devastating attacks were carried out by incels: those who seek to gain unfettered access to women's bodies by redrawing the hierarchy of the sexes in order to ensure the subjugation of women. For all of these men, masculinity is a political project, and the events at the Capitol were one episode in a growing movement. From the US and Canada to New Zealand, from Poland to Brazil, right-wing extremists, religious fundamentalists and male supremacists are coming together in order to translate their reactionary dreams of male domination into politics, underscoring the masculine roots of the authoritarian backlash.

Postmemories of Terror focuses on how young Argentineans remember the traumatic events of the military dictatorship (1976-83). This fascinating work is based on oral histories with sixty-three young people who were too young to be directly victimized or politically active during this period. All were born during or after the terror and possessed an entirely mediated knowledge of it. Susana Kaiser explores how the post-dictatorship generation was reconstructing this past from three main sources: inter-generational dialogue, education and the communication media. These conversations discuss selected and recurrent themes like societal fears and silences, remembering and forgetting, historical explanations and accountability. Together they contribute to our understanding of how communities deal with the legacy of terror.
