OFDM is an efficient modulation technique for wideband digital communication and adopted in many wireless standards. A major drawback of OFDM modulation is the high Peak-to-Average Power Ratio (PAPR) of the transmitted signal which limits its applications in communication systems. Traditionally, OFDM is implemented using FFT. On the other hand, OFDM can be(More)
In this paper we reflect on MAP-it: a participatory mapping method and toolkit, containing a map, sticker sheets, a scenario, etc. It enables designers to moderate participatory design processes through workshops in which people from different backgrounds collaboratively reflect on and set up new projects. In several test mappings during our research, we(More)

This paper departs from the idea that participatory design workshops take on the form of exchanges of viewpoints, wherein none of the involved designers, participants or objects completely define the process of exchange and its outcomes. This raises the question how this multidirectional process can still be moderated. We propose that designers take on a(More)
'Keep Forget' is a Participatory Design project that focuses on transforming location-based memories and stories into tangible objects (i.e. artefacts). During the project (2013-2016), the residents of the neighbourhood of Winterslag as well as other local actors (the city, local organisations, etc.) were involved ins sharing their stories and (individual)(More)
