The technology allows to optimize the transmission rate, power or energy efficiency of a communications system with very low complexity. Partners to further develop the system and/or to establish commercial agreements along with technical cooperation are sought.

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.

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.

Universidad de Alcalá-OTRI posted this:Signal demodulating devices through a Wavelet OFDM receiver (for broadband signal reception)A research group of the Department of Signal Theory and Telecommunications of the Universidad de Alcalá has developed demodulation procedures for broadband signal reception. The proposed approach implements a Wavelet OFDM receiver, based on modulated filter banks according to the Extended Lapped Transform. This modulation technique has been proposed in data transmission for broadband power line communications (PLC), and presents the following characteristics: a) a greater spectral separation between the subcarriers; b) more noise immunity, including narrow band interference impulsive. A block channel equalization is also incorporated in the frequency domain, which includes a parallel sine-modulated filter bank. This invention can be used in all those techniques with multicarrier modulation based on Wavelet OFDM in the transmitter. The group looks for ICT companies to achieve manufacturing agreements and commercial agreements with technical assistance.

The current commercial models are usually based on small programmes done in Excell that evidently does not have the optimum potential of these heuristic developed in languages of high-level programming. These tools provide the necessary information to the cost model LRIC Bottom Up defined by the European Commission. Operators and governments of different countries already have used the tools that are described in this document.

Nowadays, it is possible to perform a lot of actions at home and there are not temporal restrictions. The electronic tickets are an example, we can buy a transport ticket or a movie ticket. In this sense, the smart-phones are a key element because users can buy the e-ticket from any place and can carry tickets while they are moving, and validate them in order to get access to the service. Moreover, the e-ticketing systems must offer the same properties of the paper tickets, i.e. they must be secure, anonymous and transferable. Our system provides a secure method that is anonymous and that allows the ticket transferability between users. We are interested in licensing our method. The e-ticketing system proposed can be used in differents services, so that service providers can adapt the system in order to meet their requirements. The system provides to the users the same properties of some of the paper tickets. The tickets are anonymous and users can transfer them to other users without the interaction of the ticket issuer or the provider. The privacy for the users must be seriously taken into account. The acceptance of a system that could control all the movements of a determined user could lead to a privacy threat. Thus, the users could be reluctant to use a system without the proper privacy protection. Moreover, each user could send her ticket and grant permission to another user. Nonetheless, if one user does some fraud the anonymity can be revoked and the user is identified. The system can be deployed in the cloud for the service providers. The users can use their smart-phones to obtain, use or transfer the e-tickets.

The Delayed Dictionary Compression (DDC) family of algorithms was invented by Prof. Yossi Matias and Mr. Raanan Refua. The motivation was to release the bottleneck of low level infrastructures - data transfer links. Current data compression techniques for packet networks allow a good compression and a poor latency, or poor compression ratio and a good latency. Project ID : 4-2012-319
