Reducing the number of RF chains in a multi-antenna system is a central effort in next generation communication systems, as the RF components grow more expensive and area consuming. This issue had been the subject of many of the latest researches in the communication area and is also of great interest in the industry side. One common method to allow for RF chains reduction is to shift some of the...

Massive MIMO systems are considered as one the leading enabler of 5G wireless communication. In this technology, the transmitter and receiver are equipped with very large number of antennas. This can potentially allow for higher data rates and better spectral efficiency. One of the main challenges is massive MIMO system is the hardware complexity. When considering hundreds of antennas, dedicated RF chain per antenna like in traditional MIMO systems is...

Project description: Super resolution fluorescence microscopy techniques are an ensemble of light-microscopy techniques which achieve spatial resolution beyond the limitations imposed by the diffraction of light. On the other hand, since its introduction in 1983, deconvolution microscopy has become a key processing tool for the visualization of cellular structures of fixed and living specimens in three dimensions and at sub-resolution scale. Deconvolution is also referred to as an inverse problem,...

The MWC efficiently samples and reconstructs sparse wideband, or multiband, signals below the Nyquist rate,without a priori knowledge of their support. However, in some applications, the transmissions composing the wideband signal are known to belong to certain function families, such as CW, pulses with known shapes,chirps… The unknown parameters are the carrier frequencies, delays, amplitudes, scaling factors, symbol rates… In this project, our goal is to incorporate this a priori...
