Living and dealing with RF impairments in communication transceivers

This paper provides an overview of the sources and effects of the RF impairments limiting and rendering the performance of the future wireless communication transceivers costly as well as hindering their wide-spread use in commercial products. As transmission bandwidths and carrier frequencies increase effect of these impairments worsen. This paper studies and presents analytical evaluations of the performance degradation due to the RF impairments in terms of bit-error-rate and image rejection ratio. The paper also give highlights of the various aspects of the research carried out in mitigating the effects of these impairments primarily in the digital signal processing domain at the baseband as well as providing low-complexity hardware implementations of such algorithms incorporating a number of power and area saving techniques.

Film as an archive for colonial photographs: activating the past in the present

This practice-led research looks at the ways in which the colonial archive, and the colonial photographic archive in particular, can be reconstructed to produce new critical histories. The research argues for the potential of the moving image as a tool for re-staging colonial archives, as a means of generating responsible ways of looking at, and of engaging with our troubled collective pasts. In my practice I mix the photographic archive of the Anglo-Iranian Oil Company(which became BP) with my family’s photographs from Iran, and with the documentation and narrativization of my encounter with both of these sets of materials, within the moving image. Through this process I address questions about the nature of the photographic archive and the search for historical meaning within it; the question of the researcher’s position within the archive and within the history she produces; and I investigate the affective power of colonial photographs within film and the experience of untimeliness which they produce. While addressing problems associated with the failure of photographic archives to offer access to any stable, transparent meaning, I show how engaging with slippages of meaning can produce other kinds of historical knowledge. But I also argue that attending to the impression of the ‘real’ produced by the colonial photograph as it appears within film, makes the past felt in the present tense, in ways that draw attention to the responsibility of being an onlooker in a situation of injustice. In addition I show how registering the place and time of the researcher within the new filmic archive in motion produces an effective means of imaginative time travel and a lively experience of history.

Masculinities and Narrating the Past: Experiences of Researching White men who Refused to Serve in the Apartheid Army

This article reflexively analyses the construction of identity and the representation of the past in qualitative interviews with white men who refused to serve in the apartheid-era South African Defence Force (SADF). The contribution that white male objectors made to the anti-apartheid struggle occupies an ambivalent and increasingly forgotten aspect of South African liberation history. In a reflexive research story, I argue that the gendered, sexual and raced subjectivities of the researcher and researched are central to the joint construction of meaning in the interview and in the creation of self-narratives. The article also analyses how the narratives of white men's involvement in resisting apartheid are defined by their perceived position and wider power struggles in contemporary South Africa.
