We consider an uplink multicarrier system with multiple video users who want to send compressed video data to the base station. In the time domain, we model the time varying channel using Jakes’ model, and in the frequency domain, each subcarrier is assume ...

Small antennas, or more specifically, electrically small antennas, are passive radiating elements whose size is much smaller than the operating wavelength. The current wireless application systems usually have size constraints that, for the most common ope ...
A self-sustained Radiation-Pressure driven MEMS ring OptoMechanical Oscillator (RP-OMO) attaining an anchor-loss-limited mechanical Q-factor of 10,400 in vacuum has posted a best-to-date phase noise of -102 dBc/Hz at a 1 kHz offset from a 74 MHz carrier, m ...
The ever-growing global internet traffic has increased demand for higher speed data transmission. As the bandwidth requirements of wireline links increase, extensive digital equalization techniques are required to compensate for the high-frequency channel ...
Surface Acoustic Wave (SAW) technology is omnipresent in the devices around us today, mainly used as passive bandpass filters in most radio systems like smartphones and TV antennas or as delay lines in telecommunications. More recently, the possibility to ...
The exponential growth in computing power and multimedia services has caused a tremendous increase in data traffic in recent years. This increase in data traffic brings a strong demand for data bandwidth of electrical input/output (I/O) links and pushes th ...

OBJECTIVES: For turbo spin echo (TSE) sequences to be useful at ultra-high field, they should ideally employ an RF pulse train compensated for the B 1 + inhomogeneity. Previously, it was shown that a single kT-point pulse designed in the small tip-angle re ...

Vision-based background subtraction algorithms model the intensity variation across time to classify a pixel as foreground. Unfortunately, such algorithms are sensitive to appearance changes of the background such as sudden changes of illumination or when ...
This paper brings additional light on the previously proposed two-step tracking algorithm for E1 CBOC tracking. More specifically, assessment of the different DLL and PLL tracking loop architectures are analyzed, taking into consideration coherent and non- ...
FP7 GAMMA-A project is a European project with the objective to develop a 3-frequency GPS/Galileo receiver concept for automotive mass-market applications. This receiver shall build on the excellent properties of the new and modernized wide-band Galileo an ...
