Analog Baseband-IC for Dual Mode Direct Conversion Receiver
- Proceedings of the European Solid-State Circuits Conference
, 1996
"... This paper presents a circuit design and implementation for the analogous filter and amplifier sections of a direct conversion receiver. Dual-mode operation is achieved by switching the LP-filters' cut-off frequency to meet DECT and DCS 1800 specifications alternatively. An op-amp-based inte ..."

Subspace Communication
, 2014
"... We are surrounded by electronic devices that take advantage of wireless technologies, from our computer mice, which require little amounts of information, to our cellphones, which demand increasingly higher data rates. Until today, the coexistence of such a variety of services has been guaranteed by ..."

1Compressive Link Acquisition in Multiuser Communications
"... Abstract—An important receiver operation is to detect the presence specific preamble signals with unknown delays in the presence of scattering, Doppler effects and carrier offsets. This task, referred to as “link acquisition”, is typically a sequential search over the transmitted signal space. Recen ..."

MPEG-4 for Interactive Low-delay Real-time Communication
, 2003
"... ii Internet broadcasting techniques are wide spread and have been the focus off many research projects. Due to high transmission delays these systems often lack interactivity. This thesis introduces a new streaming system to deliver real-time video and audio data with low-delays across the Internet. ..."

Abstract Multichannel Communication in Contiki's Low-power IPv6 Stack
"... Vast majority of wireless appliances used in household, industry and medical field share the ISM frequency band. These devices need to coexist and thus are challenged to tolerate their mutual interference. One way of dealing with this is by using frequency hopping; where the device changes its radio ..."
