Performance of an adaptive homodyne receiver in the presence of multipath, Rayleigh-fading and time-varying quadrature errors

In this paper, we carry out a detailed performance analysis of the blind source separation based I/Q corrector operating at the baseband. Performance of the digital I/Q corrector is evaluated not only under time-varying phase and gain errors but also in the presence of multipath and Rayleigh fading channels. Performance under low-SNR and different modulation formats and constellation sizes is also evaluated. What is more, BER improvement after correction is illustrated. The results indicate that the adaptive algorithm offers adequate performance for most communication applications hence, reducing the matching requirements of the analog front-end enabling higher levels of integration.

Confronting law affectively: encounters of a Patpong sex tourist

When considering spaces of sex-work such as Patpong in Bangkok, Thailand, the inclination is to be drawn into habitual debates concerning the legitimacy of sex-work and the clear objectification of sex-workers. While these concerns are valid and real, there are significant absences in terms of the theoretical mapping of the space, such as the affect of the presence of law, bodies, space and the sexual encounter itself. Law emerges as the most significant presence, since it both forms the transactional surface of Patpong and produces the confusion and revilement that results from the confluence of cold legal exchange with the tactile intimacy of the sexual encounter. This text explores the ethnographic space of Patpong in order to understand ways in which law’s transactional, effective surface is both embodied through subjectivication and spatially emplaced, yet also disrupted through the affective agency of the bodies and spaces it enfolds in order to produce this surface. This exploration will point to the limitations of law’s effective surface and suggest ways in which law might be located within a regime of affect, which returns the law to the body it subjectivises.
