Universidad de Alcalá-OTRI posted this:Novel Synchronization Process for Multi-carrier or Single-carrier CommunicationsThe research group “Communications, Multirate Systems, and Biomedical Engineering” of the University of Alcala presents a novel synchronization procedure for multicarrier or single carrier systems for narrowband and broadband communications. This procedure allows a precise estimation of the symbol timing offset (STO), and a coarse estimation of carrier frequency offset (CFO). The procedure is based on the inclusion of symmetric extensions in the transmitted symbols for the synchronization, which makes it useful not only for communications systems based on the discrete Fourier transform, but also for transceivers based on the discrete cosine transform (DCT). Among its main applications are communications through single-mode optical fiber, powerline communications, wireless and wireline systems, and in general, all the techniques that use multicarrier and single carrier modulations. The group seeks companies from the telecommunications sector to sign technical cooperation agreements, commercial agreement with technical assistance and patent licensing agreements.
UATEC - Unidade de Transferência de Tecnologia posted this:Distributed interference cancelation based on outdated channel gain informationA group of researchers from a Portuguese university has developed a technology for distributed communication systems where several pairs of transmitters/receivers communicate simultaneously using the same resources. The invention aims to increase the throughput of current cellular communication systems. The advantages of this technology in relation to existing solutions are: 1) the throughput is enhanced and proportional to the square root of the number of transmitter/receiver pairs. 2) the interference is canceled using only outdated channel gain information and the interference removal procedure is distributed. The university is looking for companies on the wireless communications arena interested in improving the capacity of their communication systems.

Northeastern University's Center for Research Innovation posted this:A New E-Field Writable Magnetic Random Access Memory Based on MultiferroicsCurrently, magnetic random access memories (MRAMs) use a magnetic field to control corresponding magnetic states. Such systems are comparatively bulkier and are associated with high-power consumption. With ever changing life-style; the demand for faster, smaller and ultra-low power memory systems is significantly increasing. This approach allows for the development and use of a novel electric field (E-Field) controllable MRAMs based on multi-ferroics.

PhotonDelta posted this:Method and arrangement for microwave signals transmission through a multimode fiberThe invention provides a solution for the direct transportation of analog electrical signals, in particular radio signals, via a multi-mode optical fiber, so that it will be possible to transmit the transferred radio signal without any further signal processing at the base stations. Especially if a large number of base stations are used, as in the case of wireless networks as explained in the foregoing, it will be advantageous to keep the base stations as simple as possible. Not only does this provide a direct financial benefit as regards the cost of the base station itself, but it also enables a considerable saving on maintenance and repair costs of the network.

University of Vigo posted this:Suppression of Impulsive Noise for 4G cell phonesUVIGO telecom engineers have developed a novel methodology to suppress the impulsive noise present in Long Term Evolution (LTE) cell phone systems. These systems that utilize multiple-input multiple output (MIMO) techniques are already used in fourth generation (4G) cell phones and are expected to undergo further development in a near future. The presence of impulsive noise can be detected comparing the signals received by different antennas, the subsequent application of a enhanced algorithm leads readily to the suppression of the deleterious effect of the impulsive noise on the radio signal. To date, no other methods have been specifically developed for LTE.
University of Vigo posted this:Suppression of Impulsive Noise for Power Line CommunicationsPower Line Communications (PLC) is an emerging field that enables to carry data on a conductor that is also used simultaneously for AC electric power transmission or electric power distribution to consumers. The widespread use of these technologies is however, compromised by the presence of impulsive noise that arises from interferences generated by devices connected to the power line. Therefore removal of impulsive noise is critical to get a high performance of PLC systems. UVIGO researchers have developed a novel methodology to mitigate impulsive noise by monitoring those carriers of the radiofrequency spectrum that are free of transmission in PLC systems. The identification of the noise signals allows its selective removal keeping the quality of the overall PLC signal.
