Design of a quantum based single-bit full-adder with greater energy efficiency than currently existing transistor-based technologies. The encoding of information in only a few electrons trapped inside a semiconductor system of three quantum dots allows the execution of a full-adder through coherent […]

Method to perform modulation over pilot symbols in communications systems employing quadrature amplitude modulation (QAM). It allows to either increase the delivered bit-rate of the transmission system while keeping the same operating bandwidth and/or reduce the required signal-to-noise ratio (SNR) […]

Smart seat cover for vehicle seats that includes a vital signs sensors network, embedded in upholstery for monitoring the physiological state of the driver or passengers. The integrated sensors monitor subject’s breathing (bio-radar) and several comfort parameters, such as humidity, pressure and tem[…]

Outdoor localisation system based on magnetic landmarks – magnetic anomalies that distort the expected geomagnetic field due to strong local magnetic fields, oftentimes originated by fixed man-made structures. This technology proposes to leverage those landmarks as signatures for localisation purpos[…]

Algorithm in the scope of carrier phase recovery for digital signal processors of multicarrier optical systems. It allows an unprecedented separate monitoring and compensation of the contributions of each of the two optical sources to phase noise. This method presents considerable gains in links hig[…]

Phased array antennas are suitable for massive MIMO wireless communications, of which 5G and satellite communications are paradigmatic examples. These 3 patent families propose a photonic beamforming system that is able to process a large number of RF signals with a very broad bandwidth, something t[…]

Network of wireless and passive sensors (without batteries), using a set of unique sensors which use a frequency for the data transfer (obtained by sensors) and another frequency for the reception of energy that is emitted by transmitters that power the sensors. For this, only a central data recepti[…]

New physical layer security technology comprising an innovative secure channel training scheme that protects a two user non-orthogonal multiple access (NOMA) system against eavesdropping attacks. This technology improves the confidentiality level of the current and future wireless systems, more spec[…]

New method aimed to enhance the overall throughput of communication systems by utilizing outdated channel gain information for distributed interference compression and removal. The technology targets a dynamic environment with several distributed transmitters and receivers sharing a common medium.[…]
