Abstract: A system, method and device for error detection/estimation in OFDM communications systems is proposed. The disclosed mechanism allows an efficient error prediction in a received packet, without having to perform full FEC decoding of the packet that could impair the overall latency of the system due to the time spent in a complete FEC decoding of the packet. In order to do that, it generates a decision variable with the aim to check whether a received packet has errors or not, after performing only partial FEC decoding of the packet, without either resorting to the use of error-detection codes.

Abstract: Methods and systems to perform textual queries on voice communications. The system has an index service for storing a audio content data sets for voice communications. The audio content data sets include at least three audio content data sets for each voice communication. The three audio content data sets include a first audio content data set generated using a speech-to-text conversion technique, a second audio content data set generated using a phoneme lattice technique, and a third audio content data set generated using a keyword identification technique. The system includes a search engine configured to: receive search criteria from a user, the search criteria having at least one keyword; search each of the first, second and third audio content data sets for at least a portion of the plurality of voice communications to identify voice communications matching the search criteria; and combine the voice communications identified by each search to produce a combined list of identified voice communications.

Abstract: A method to generate a wireless waveform for use in a wireless communication system, a wireless communication system and computer program product thereofThe method comprises the generation of a waveform for application in the wireless communication system characterized by significant phase noise, Doppler spread, multipath, frequency instability, and/or low power efficiency by at the transmitter side: creating a discrete-time instantaneous frequency signal {tilde over (f)}[n]; appending a cyclic prefix with length LCP to the beginning of the discrete-time instantaneous frequency signal {tilde over (f)}[n]; constructing a discrete-time unwrapped instantaneous phase φ[n]; constructing a discrete-time complex baseband signal, and appending at the beginning a Constant Amplitude Zero Autocorrelation, CAZAC, signal of length LCP for multipath detection; and passing the constructed discrete-time complex baseband signal through a digital-to-analog, DAC, converter to yield the continuous-time radio frequency signal s(t) after conversion to the carrier frequency.

Abstract: A system and method for managing subscriber mobile devices comprising: a home network (400) of a first mobile network operator (MNO1), in which data associated with at least one physical SIM of a subscriber device with an embedded SIM card (eUICC) is obtained, and a destination network (300) of a second mobile network operator (MNO2) which the device travels to, obtaining static data and dynamic data associated with at least one virtual SIM (503, 603) of the device. The dynamic data comprise a subscriber authentication key (Ki) and is obtained from a SIM provider platform (500, 600) on which the destination network (300) relies. The static data comprise IMSI/MSISDN identities and is stored in a pool (202) of the destination network (300).For a given virtual SIM, it is checked whether there is an association in a mapping table (106) of the first mobile network operator (MNO1) between the static data from the pool (202) and the physical SIM data from the home network (400).
