Abstract: La voie d'émission d'un dispositif radiofréquence du type à conversion directe comporte un étage de transposition de fréquence d'émission apte à transposer un signal en bande de base dont la fréquence se situe dans une plage initiale de fréquences en un signal radiofréquence. Dans au moins une première phase de détection on génère un signal d'étalonnage en bande de base ayant une fréquence d'étalonnage choisie dans ladite plage initiale, on multiplie par lui-même un signal d'étalonnage transposé issu dudit signal d'étalonnage en bande de base et prélevé en aval de l'étage de transposition de fréquence d'émission de façon à obtenir un signal transposé élevé au carré, on filtre le signal transposé élevé au carré de façon à en éliminer les composantes radiofréquences, et on mesure au moins le niveau de la composante fréquentielle du signal filtré ayant ladite fréquence d'étalonnage (f i ).

Abstract: The calibration is performed tone per tone during interframe spacing. A peak detection is used for measuring (42) the level of the corresponding signal and a gain correction coefficient (GCCFi) is stored for correcting the digital complex modulation coefficients provided by the mapping means.

Abstract: The method of notching the transmission band of an analog signal to be transmitted and including sub-carriers to be modulated from digital modulation coefficients respectively associated to said sub-carriers, said method comprises providing (30) an initial digital signal from successive frequency-domain groups each containing said digital modulation coefficients respectively associated to said sub-carriers, filtering (31) said initial signal with a frequency resolution greater than the frequency resolution of said frequency-domain groups in order to remove frequencies corresponding to said sub-carriers to be removed and windowing (32) said filtered signal using a windowing mask (WMSK) having a representation in the frequency-domain including a main lobe and secondary lobes, the power spectrum of said lobes decreasing faster than the inverse of the frequency squared.

Abstract: The LDPC decoder (1) for decoding codewords, comprises processing means for updating messages exchanged iteratively between variable nodes (VN i ) and check nodes (CN i ) of a bipartite graph of said LDPC code. The decoder architecture is a partly parallel architecture clocked by a clock signal. The processing means comprises P processing units (PU i ). First variable nodes (IN i ) and check nodes (CN i ) are mapped on the P processing units (PU i ) according to two orthogonal directions. The decoder comprises P main memory banks (MMB i ) assigned to the P processing units (PU i ) for storing all the messages iteratively exchanged between said first variable nodes (IN i ) and the check nodes (CN i ). Each main memory bank (MMB i ) comprises at least two single port memory partitions (MP i ) and one buffer (BUF i ), the decoder also comprises a shuffling network (SN) and a shift memory (SM).

Abstract: The invention relates to a coupling structure for coupling optical radiation, i.e., light, between an optical fibre and an optical device, e.g., a laser diode or a photodiode, said coupling structure comprising an optical through-via which guides the optical radiation to or from the optical fibre. According to the invention, light exiting the fibre travels through a guidance channel so as it remains substantially confined to a narrow optical path that mimics the fibre core. Conversely, light enters the fibre after having travelled through the guidance channel. The guidance channel comprises a first core region, the “channel core”, having first refractive index surrounded by a second region, the “channel cladding” having a second refractive index smaller than the first refractive index. The coupling structure including the guidance channel is preferably made of semiconductor-based material, more preferably of silicon-based material. The guidance channel comprises preferably silicon oxide. The coupling structure further comprises a fibre drive-in element, which facilitates insertion and alignment of the optical fibre to the guidance channel.

Abstract: Method for blindly detecting a channel:, like e.g. a HSDPA high speed shared control channel, possibly intended for a designated user equipment among n channels (HS-SCCH1,...,HS-SCCHn) received in parallel by said designated user equipment during a given duration, each channel (HS-SCCH1,...,HS-SCCHn) received during said duration carrying encoded data masked with an identifier associated to a user equipment. The method comprises a selecting phase comprising a demasking step demasking the received masked encoded data of each channel with the identifier of said designated user equipment, a decoding step decoding the demasked encoded data of each channel to obtain a set of digital decoded data for each channel, a calculating step calculating, from each set of digital decoded data, a global information representative of a confidence in digital data received on the physical channel, and a detecting step detecting said channel using said global information.
