“…Moreover, the analog-frontend complexity of the proposed receiver is compatible with the more “classical” receivers, e.g. sliding-IF receiver [2], with the only additional frontend components being the frequency quadrupler, the bandpass, filter and the phase shifters. On the other hand, reducing the digital signal-processing load has also some drawbacks, like having no channel equalization, which limits the application scenarios to short distance line-of-sight (LOS) channel conditions (e.g.…”

This paper presents a hardware efficient receiver architecture, to be used in low-cost, ultra-high rate 60 GHz wireless communication systems. The receiver utilizes a simple, feed-forward carrier recovery concept, performing phase and frequency synchronization in the analog domain. This enables 1-bit baseband processing without a need of ultra-high speed and high precision analog-to-digital conversion, offering a strong simplification of the system architecture and comparatively low power consumption. In a first prototype implementation, the receiver is realized in a low-cost SiGe technology as two separate ICs: the 60 GHz/5 GHz downconverter, and the intermediate frequency synchronous demodulator. The simple synchronous reception concept is experimentally validated for up to 3.5 Gbit/s data rate, which constituted the limit of the existing experimental setup. Furthermore, the downconverter demonstrates that low-cost technologies (fop/fmax ~ 0.75) can be used to realize short-range data links at 60 GHz, with low-noise amplifiers in a more performant technology as needed.

“…This sounder architecture covers most of the assigned 60 GHz spectrum, so facilitates analyzing data (in post-processing) for four different sub-bands as established at the IEEE 802.15.3c PHY channelization [4], i.e., from 59.40 to 61.56 GHz, from 61.56 to 63.72 GHz and from 63.72 to 65.88 GHz. Also the narrow band channel plan can be analyzed with this architecture, which is planned for demonstration purposes [13].…”

60 GHz technology has been proposed recently for multi-Giga-bit/s access within different application scenarios, e.g. in crowded multi-user public transportation (PT) environments. Hence, channel sounders that are used to investigate multipath propagation and multi-user access techniques including spatial diversity and beam-forming in time-variant shadowing environments require ultra-wideband (UWB) operation, multiple antennas, and real-time. This paper presents probably the first channel sounder architecture fulfilling these requirements. Moreover, an experimental study is described which is performed for planning purposes and deployment of 60 GHz WLAN/WPAN networks in PT scenarios. Coverage analysis based on different PHY channelization schemes, including multiple access point configurations and antennas is addressed for the Airbus 340cabin. Additionally, distributions of time dispersion, coherent bandwidth, and Rice K-factor in the in-cabin coverage area are presented. Specifically, a brief analysis under dynamic channel conditions due to human activities is introduced. The suitability of the 60 GHz-UWB channels sounder for PT scenarios is demonstrated. Besides, some channel results for finding the most suitable system parameters for 60 GHz access deployment of inflight-entertainment (IFE) systems are given.

“…The transceivers working at millimeter wave (MM-wave) frequencies are seen as promising for short-range applications, such as wireless USB or wireless TV and video backbone systems [1]. One of the major frequency bands in which the MM-wave systems are going to work is the 60 GHz band covering 57 -66 GHz and including all the US, European and Japanese standards [2].…”

An antenna element suitable for antenna-in-package solutions at millimeter wave frequencies is introduced. The antenna is composed of a circular patch which is fed with a folded SIW feeding network. This feeding network not only makes the array design procedure modular but also reduces the interaction of the antenna and the radio integrated in the final transceiver. LTCC technology has been used to implement the packaging idea.
