Abstract:
It comprises computing values of cognitive and personality indicators of users of a telecom operator by means of machine learning and data mining algorithms from information available in a telecom operator system extracted from Social Network Analysis metrics, Call Detailed Record information and commercial information of said users stored in an operator's Data Warehouse and Customer Relationship Management systems as well as information from previous surveys, or questionnaires, answered by a representative sample of users as an input of said machine learning and said data mining algorithms. The method involves building a complex computer model that infers the values of the psychological dimensions of said users by means of said machine learning and said data mining algorithms to obtain a multi-dimensional vector for each of the users.
Abstract:
The active microfilter is essentially composed of an active part, which comprises a sign inverter circuit composed of an operational amplifier (13), two resistances and the impedance to be adapted (12), and a passive part which comprises capacitors, coils and resistances. The active microfilter is arranged in an auto-installable device which comprises a circuit for supplying the active part; wherein the aim is to eliminate the reflections caused by line sections, without adaptation, which interfere with the correct operation of the network when accessing broadband with the VDSL2 standard.
Abstract:
The invention relates to a collaborative system for security information exchange between users, based on the fact that a determined function (whether storing or processing) is spread out at different points of a network to achieve more scalable processing and storing factors than if they were all done at one and the same point.The invention proposes architecture with a centralized element, referred to as “Central Device”, through which said user devices share information with the remaining users to finally activate an alert or rule it out.
Abstract:
A method for managing an operation in a service terminal through a remote server, wherein said service terminal comprises a plurality of modules, and a communications interface configured for communicating with said remote server, wherein said remote server comprises a plurality of applications and a communications interface. The method comprises the following steps: generating an event as a response to a user interaction with one of said modules of the service terminal; associating an information to said event; sending said information to the remote server through said communications interface; processing said received information in the remote server and running an application which obtains a response to the information associated to said event; sending said response to the service terminal through the communications interface; processing said response and identifying the module of the service terminal affected by said response; and interacting with said module by performing an operation in the service terminal.
Abstract:
Method, system and computer program for real time synchronizing an audio file and a video file in a multimedia device. The present invention determines the optimum alignment path between the audio signal of the audio file and the audio track signal of the video file, starting from an initial path and performing a post-alignment processing to improve the user satisfaction when playing.
Abstract:
A method and system for optimizing the performance of spatial multiplexing techniques in MU-MIMO wireless systems comprising subsectors where the presence of significant correlation between antenna elements can impair the performance of MU-MIMO techniques. The proposed solution ensures optimum selection of a specific combination of transmit antenna elements and receive antenna elements that maximizes MU-MIMO performance.
Abstract:
Proposed are a computer-implemented method for accelerating convergence in the training of generative adversarial networks (GAN) to generate synthetic network traffic, and computer programs of same. The method allows the GAN network to ensure that the training converges in a limited time period less than the standard training period of existing GAN networks. The method allows results to be obtained in different use scenarios related to the generation and processing of network traffic data according to objectives such as the creations of arbitrary amounts of simulated data (a) with characteristics (statistics) similar to real datasets obtained from real network traffic, but (b) without including any part of any real dataset; diversity in the type of data to be created: IP traffic, network attacks, etc.; and the detection of changes in the network traffic patterns analysed and generated.
Abstract:
Method and system to dynamically associate spatial layers to beams in a FWA network operating in the millimeter-wave frequency range. A base station and a CPE are willing to wirelessly transmit and receive data through a wireless channel of the FWA network, the base station having beamforming capabilities henceforth generating multiple wireless beams. The base station performs all baseband wireless functions related for creating, keeping and managing the connections between the base station and the CPE at baseband level, wherein information is handled in the form of up to M spatial layer signals, and with no built-in capabilities for creation, detection or management of the beams. The base station also performs all necessary RF functions at millimeter-wave frequencies, including beamforming and conversion from complex baseband signals to RF signals and vice versa, and also couples the RF signals to the wireless channel.
Abstract:
A system, method and device to overcome the effects of mobility in OFDM wireless cellular networks. Individual beams are isolated and Doppler impairments are compensated so the constituent beams can reach the users in DL with ideally no Doppler impairments. Similarly in UL the signals corresponding to the different spatial beams are detected and their Doppler impairments compensated.
