Usefulness of ambient-vibration measurements for seismic assessment of existing structures

Ian Smith, Pierino Lestuzzi, Yves Sylvain Gilles Reuland

A large number of buildings in regions with low to medium seismic hazard have been designed without considering earthquake actions. Retrofitting of all buildings that fail to meet modern code requirements is economically, technically and environmentally un ...

Vector signaling with reduced receiver complexity

Mohammad Amin Shokrollahi

Methods and apparatuses are described to determine subsets of vector signaling codes capable of detection by smaller sets of comparators than required to detect the full code. The resulting lower receiver complexity allows systems utilizing such subset cod ...

26.3 A pin- and power-efficient low-latency 8-to-12Gb/s/wire 8b8w-coded SerDes link for high-loss channels in 40nm technology

Mohammad Amin Shokrollahi, Christoph Walter, Harm Cronie, Anant Pratap Singh, Klaas Lammert Hofstra, Kia Salimi

The continuing demand for higher bandwidth in serial interconnects has pushed the symbol rate of differential lanes into the high-insertion-loss region of channels. Multi-level signaling such as differential PAM-4 [1] has been used to mitigate the loss of ...

Integer-forcing Linear Receivers

Michael Christoph Gastpar

Linear receivers are often used to reduce the implementation complexity of multiple-antenna systems. In a traditional linear receiver architecture, the receive antennas are used to separate out the codewords sent by each transmit antenna, which can then be ...

An Efficient Time-frequency Algorithm for the Weak Signal Acquisition of Modernized GNSS Signals

Pierre-André Farine, Cyril Botteron, Jérôme Leclère, Vincenzo Capuano, Jia Tian, Yanguang Wang

The new GPS/Galileo/Compass signals use much longer code lengths and higher code frequencies than the GPS L1 C/A signal. As a result, they can provide improved ranging and anti-jamming performances. Unfortunately, their acquisition complexity is significan ...
