摘要： A method and device for handling write access conflicts in interleaving, in particular for high-throughput turbo decoding for wireless communication systems; the device comprises N interleaving buffers (CLk) that are respectively connected to N producers (PRk), an LLR distributor means and N single port target memories (TMk). At any time step, each interleaving buffer receives m LLR inputs from the producers and has to write up to M of these into a register bank (RBk), which comprises W registers. M denotes the maximum number of concurrent write operations supported per time step and W denotes the maximum buffer size. M and W are design parameters and are chosen for the standard case and not for the worst case. m-M producers have to be stalled whenever m is larger than M and m producers have to be stalled whenever a buffer overflow occurs (more than W LLR values). Finally, at any time step one LLR value is fetched from the register bank and written to the SRAM interleaving memory.

摘要： The present invention encloses a biometric sensor for sensing fingerprints. The enclosure (100) comprises a movable access piece (110) positionable at a plurality of positions. A sensor (130) is mounted relative to the access piece, and the access piece (110) is slidable to reveal the sensor. When the access piece (110) is in the closed position, the sensor (130) is completely enclosed and thereby protected from impacts. To access the sensor (130), the user slides the access piece (110) to an open position using the finger (120) he wishes to place on the sensor. When the access piece (110) reaches the fully opened position, the fingerprint is aligned with the sensor (130). The access piece (110) is made from a conductive material, and it is also electrically grounded. Since the user must touch the access piece (110) to reveal the sensor (130), the user is electrostatically discharged before accessing the sensor.

摘要： A resonant power converter (220) for ultra-efficient radio frequency transmission and associated methods is disclosed. In one exemplary embodiment, the invention is digitally actuated and uses a combination of a noise-shaped encoder (222), a charging switch (224), and a high-Q resonator (204) coupled to an output load (206), typically an antenna or transmission line. Energy is built up in the electric and magnetic fields of the resonator, which, in turn, delivers power to the load (206) with very little wasted energy in the process. No active power amplifier is required. The apparatus (220) can be used in literally any RF signal application (wireless or otherwise), including for example cellular handsets, local- or wide-area network transmitters, or even radio base-stations.

摘要： The actual transport format is ex ante unknown and belonging to a set of MF predetermined reference transport formats. The signal comprises a data block having an ex ante unknown number of bits corresponding to said ex ante unknown transport format, and a cyclic redundancy check (CRC) field containing a transmitted CRC word. The method comprises decoding said signal using a Maximum-a-Posteriori algorithm, said decoding step including decoding said signal considering respectively the MF possible reference formats and respectively delivering MF corresponding groups of soft output information, calculating from each group of soft output information a calculated CRC word and comparing said calculated CRC word with said transmitted CRC word, selecting all the groups for which said calculated CRC word is equal to said transmitted CRC word, and selecting the actual transport format of the encoded signal from at least one soft output information among the last ones of each selected group.

摘要： The incident signal contains a preamble including a training sequence having a series of pulses whose polarity and time shifts are defined by respective polarity code and time-hopping code. The method comprises a digital cross-correlation of the received signal with said training sequence, said cross-correlation step (101) including algebraically summing in accordance with said polarity code (a j ), windows of said received signal, the starting points of said windows being determined by said time-hopping code (c j ), and a detection step for detecting the end point (n synchro ) of the preamble from the result of said cross-correlation step. When the size of the receiving buffer, i.e. the size of the window is smaller than the number N of samples of each replica of the training sequence, it is particularly advantageous that said digital cross-correlation step be performed iteratively in a block-by-block fashion, the computation of each block being split into M slices which are computed by algebraically summing windows N/M samples long.

Further operational units (SM, LLR) are used for both Turbo-code and convolutional code. An effective harware folding scheme permits to calculate 256 states serially on 8 ACS units.
