Performance of turbo multi-user detectors in space-time coded DS-CDMA systems

Includes bibliographical references (leaves 118-123).In this thesis we address the problem of improving the uplink capacity and the performance of a DS-CDMA system by combining MUD and turbo decoding. These two are combined following the turbo principle. Depending on the concatenation scheme used, we divide these receivers into the Partitioned Approach (PA) and the Iterative Approach (IA) receivers. To enable the iterative exchange of information, these receivers employ a Parallel Interference Cancellation (PIC) detector as the first receiver stage

The Virginian Sea bibliography

The bibliography of the Virginian Sea is a compendium of literature and environmental data concerning the Middle Atlantic Bight region of the Western North Atlantic - or the United States east coast. The geographical coverage of this bibliography ineludes that region extending from 41° N latitude to 36° N latitude and out 200 miles from the coastal headlands. This volume represents the first step of an effort undertaken by the Virginia Institute of Marine Science to assess the present status of knowledge concerning the physical and chemical environment, biology, and fisheries of the Virginian Sea. We do not put forth this work as a complete bibliography of the Virginian Sea. No bibliographic effort of this scope can attain one-hundred percent coverage. Certainly, however, this bibliography is quite representative of the scientific research that has been done in the Middle Atlantic Bight. Later editions will broaden the bibliographic coverage of this work, correcting omissions as they are noted and making necessary additions. We hope that this bibliography will be useful to government, science, and the private sector; and welcome suggestions and, criticisms which would lead to its improvement

The NASTRAN User's Manual Level 16.0 and Supplement

The user's manual is restricted to those items related to the use of NASTRAN that are independent of the computing system being used. The features of NASTRAN described include: (1) procedures for defining and loading a structural model and a functional reference for every card that is used for structural modeling; (2) the NASTRAN data deck, including the details for each of the data cards; (3) the NASTRAN control cards that are associated with the use of the program; (4) rigid format procedures, along with specific instructions for the use of each rigid format: (5) procedures for using instructions for the use of each rigid format; (5) procedures for using the NASTRAN plotting capability; (6) procedures governing the creation of DMAP programs; and (7) the NASTRAN diagnostic messages. The NASTRAN dictionary of mnemonics, acronyms, phrases, and other commonly used NASTRAN terms is included along with a limited number of sample problems

Screen theory and film culture, 1977-1987.

My work in the 1970s and 1980s was developed with the evolving body of work now loosely called 'c e theory'. It centred on notions of authorship, spectatorship and art cinema with specific reference to the films of Carl Dreyer. In my research and writing on Dreyer's film Vampyr I applied the literary concept of the fantastigue to cinema, one of the first substantial theoretical contributions to a now established area of publication and research. According to one writer' this work was "probably the most ambitious attempt to apply Todorov's approach to cinema", a "notable exception" in the theoretical writing of that time. This was part of the wider movement associated with SEFT and Screen to interrogate the uncritical realism which dominated 1970s film studies. In my subsequent writing on Dreyer I explored a structuralist but more psychoanalytically informed discussion of genre, developing the concept of the "Dreyer text" as a way of bringing psychoanalytic concepts to compliment and complicate structuralist notions of authorship and genre. I was part of a loose group at Screen which was passionate both about cinema and ideas. While polemically defending the new concepts we were bringing to bear on cinema, we were equally concerned with their institutional placing. Our work concentrated both on regimes of looking allowed to the spectator by texts and their institutional placing. We focussed on political and discursive structures of the cinematic institution and developed a concept of `cinema as social practice'. In particular I pushed for a cultural critique of British Independent cinema and its institutions, which was continued in my work on screen acting. I was also instrumental in extending Screen theory to other visual arts. I felt that the sometime parochialism of film studies lay in part in its separation from analysis of other forms of visual culture. In my full context statement I wish to explore limitations in the political, semiotic and psychoanalytic models which I (as did many others) adopted at the time. What I now see as Screen theory's 'blind spots' in relation to issues of sexual orientation and race can be traced back to the problematic of this period. My own subsequent research on gay and lesbian cinema as well as film and television projects on screen acting (Acting Tapes) psychoanalysis (Between Two Worlds) and Frantz Fanon (Frantz Fanon: Black Skin White Mask) came out of dissatisfaction with that earlier project as it was then conceived. The form chosen - the essay and review - reflects the difficulty of thinking through these issues. [James Donald (ed), 'Fantasy and the Cinema', British Film Institute, London 1989] In essence my proposal involves looking back at my work around Dreyer and what one could broadly call my `film culture' work, and arguing that what was sometimes felt and described as a theory: practice division between these two domains could be more usefully thought of in retrospect in terms of two overlapping modes of theoretical production involving different notions of institution, conjuncture, subject etc. In looking again at the strengths and weaknesses of the work I am submitting here, however, I still expect key terms of subject and history, discourse and institution, to remain in place, modified and nuanced by the substantial range of work in psychoanalysis, cultural studies and queer theory that Screen in part engendered and which my work participated in

The dynamics of innovation: newness and novelty in the Athens of Aristophanes

This study looks at the dynamics of innovation: why innovation occurs, what newness means in diverse areas of life, how social, cultural and individual attitudes to novelty interact, and the wider impact of innovation. The historical focus is ancient Athens, a society well known for its originality and creativity. Despite Athens' well-known competitiveness and flair for innovation, classical historians have tended to emphasise its traditionalism and respect for the past. However, the comedies of Aristophanes testify to the deliberate pursuit of innovation and to the effects of rapid and wide-ranging change in the late fifth and early fourth centuries B.C. They are adduced, together with other sources for the period, as evidence for the kinds of innovation that took place in politics, law, religion and warfare, as well as in specialist skills (technai) such as rhetoric, the visual arts, music, and medicine. The sources reveal diverse reactions, ranging from ambivalence and anxiety to excitement and optimism, to the experience of newness in these culturally key areas of Athenian life. Attitudes and behaviour differed between individuals and social groups, depending on the area of innovation. A combination of factors served to encourage the drive to innovate: material circumstances such as commercialism, war, and imperial rule; social pressures such as competitiveness, democratic openness, and the desire for acclaim; and technical imperatives such as the pursuit of accuracy, efficacy, and originality. The proliferation of tools of verbal communication (specifically rhetoric and writing) to express and record new ideas; is a pervasive theme. In conclusion, a broad trend is discerned for the period, showing Athenians towards the end of the fifth century to have been unusually interested in the meaning and possibilities of innovation. Aristophanes' characterisation in particular of the climate of newness suggests an intriguing historical analogue to recent discourses of postmodernity
