The methods are evaluated on ability to estimate the remaining useful life of rolling element bearing. Run-to failure vibration and temperature data is used in the analysis. The sampled prognostic methods include wear-temperature correlation method, health state estimation using temperature measurement, a multi-model particle filter approach with model parameter adaptation utilizing temperature measurements, prognostics through health state estimation and mapping extracted features to the remaining useful life through regression approach. Although the performance of the methods utilizing the vibration measurements is much better than the methods using temperature measurements, the methods using temperature measurements are quite promising in terms of reducing the overall cost of the condition monitoring system as well as the computational time. An ensemble of the presented methods through weighted average is also introduced.

To accommodate this demand, advanced terahertz signal processing techniques need to be investigated. Parallel Sequence Spread Spectrum (PSSS) is a physical layer (PHY) baseband technology that seems to be suited for being used for ultra-high speed wireless communication since the receiver architecture is especially simple and can be implemented almost completely in analog hardware. In this paper, a PSSS modulated signal at a chip rate of 20 Gcps with a spectral efficiency of (only) 1 bit/s/Hz is transmitted using a linearity limited 240 GHz wireless frontend. PSSS transceiver models are realized offline in MATLAB/Simulink. The PSSS transmitter generates the PSSS modulated symbols that are loaded onto an Arbitrary Waveform generator (AWG) and then transmitted using the available 240 GHz wireless frontend. A Digital Storage Oscilloscope (DSO) samples and stores the received signal. The PSSS receiver performs synchronization, channel estimation and demodulation. For a coded data rate of 20 Gbps, an eye opening of 40% and a BER of 5.4·10 -5 has been measured. These results are highly promising to achieve data rates of up to 100 Gbps with PSSS modulation using a RF-frontend having higher linear operating range and thus allowing increasing the bandwidth efficiency to 4 b/s/Hz.}}, author = {{KrishneGowda, Karthik and Messinger, Tobias and Wolf, Andreas and Kraemer, Rolf and Kallfass, Ingmar and Scheytt, Christoph}}, booktitle = {{ICUWB 2015}}, title = {{{Towards 100 Gbps Wireless Communication in THz Band with PSSS Modulation: A Promising Hardware in the Loop Experiment}}}, doi = {{10.1109/ICUWB.2015.7324520}}, year = {{2015}}, } @inproceedings{24291, abstract = {{In this paper, a miniaturized 122 GHz ISM band FMCW radar is used to achieve micrometer accuracy.

The state-of-the-art antenna integration and packaging technologies are extensively studied, and an antenna design flow is proposed. A number of integrated antenna designs by applying different integration approaches and technologies, i.e. on printed circuit board (PCB), on-chip and in Benzocyclobutene (BCB) above-wafer process, are presented. The designs target not only high performance, but also the practical considerations of low-cost, feasibility, better reliability, and good reproducibility. They cover the industrial, medical, and scientific (ISM) bands of 60 GHz, 122 GHz, and 245 GHz in the millimeter-wave range with outstanding performance in a low-cost fashion by applying innovative, appropriate integration methods and sophisticated design. By applying the localized backside etching (LBE) process the presented on-chip antennas achieve measured peak gains of 6–8.4 dBi for above 100 GHz applications with simulated efficiencies of 54–75%. These figures are comparable to that of on-board or in-package antennas. To the best of my knowledge, the achieved gain of 7.5–8.4 dBi in the band of 124–134 GHz for the 130 GHz on-chip double folded dipole antenna is the highest reported result to date for planar on-chip antennas based on low-resistivity silicon technologies. System demonstrators with integrated antennas are realized and measured. The 60 GHz demonstrator with on-PCB differential bunny-ear antenna and a novel bond-wire compensation scheme achieves a data rate of 3.6 Gbit/s over a 15-meter distance, which was the best reported analog front-end without beamforming function in silicon technology regarding both the data rate and transmission distance at the time of its publication. A 245 GHz single-channel transmitter and a single-channel receiver with integrated on-chip antennas are also demonstrated. An effective isotropic radiated power (EIRP) of 7–8 dBm is achieved for the transmitter, which is the highest reported value at 245 GHz for a SiGe transmitter with a single antenna so far. Furthermore, the receiver has the highest reported integration level for any 245 GHz SiGe receiver. A 245 GHz 4-channel-transmitter array with integrated on-chip antenna array is also realized to achieve spatial power combining, which offers 11 dB higher EIRP than a single-channel transmitter. From the presented results of the thesis it is feasible to realize high performance integrated planar antennas in the entire millimeter-wave range and beyond in a cost-effective fashion. }}, author = {{Wang, Ruoyu}}, publisher = {{Verlagsschriftenreihe des Heinz Nixdorf Instituts, Paderborn}}, title = {{{Integrated Planar Antenna Designs and Technologies for Millimeter-Wave Applications}}}, volume = {{338}}, year = {{2015}}, } @inproceedings{24293, abstract = {{Parallel Sequence Spread Spectrum (PSSS) is a physical layer baseband technology wherein parallel data streams are transmitted simultaneously by spreading them using orthogonal codes.
