Abstract: The invention relates to a method for producing a photodiode contact for a TFA image sensor which includes a photodiode, produced by deposition of a multilayer system and a transparent conductive contact layer on an ASIC circuit that has been coated with an intermediate metal dielectric component and that has vias in a photoactive zone which are arranged on a pixel grid. Said vias extend through the intermediate metal dielectric component and are linked with respective strip conductors of the CMOS-ASIC circuit. A pixel-grid structured barrier layer, and on top thereof a CMOS metallization, are arranged on the intermediate metal dielectric component. The aim of the invention is to improve the characteristic variables of the photodiode by simple technological means. This object is achieved by removing at least the CMOS metallization present on the CMOS-ASIC circuit in the area of the photoactive zone except for the structured barrier layer and subsequently applying the multilayer system of the photodiode and the conductive transparent contact layer to the CMOS-ASIC circuit.

Abstract: A rake receiver uses a delayed version of the received sequence and a delayed version of a scrambling code. The flexible hardware structure of the time-aligning and descrambling unit includes at least two delay chains and one multiplier. By controlling two multiplexers, the delayed versions of the received sequence can be multiplied with an arbitrary scrambling code having an arbitrary phase. During one chip period, one multiplication is performed for each path to be processed.

Abstract: An 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. A method includes a digital cross-correlation of the received signal with the training sequence. The cross-correlation algebraically sums in accordance with the polarity code windows of the received signal. The starting points of the windows are determined by the time-hopping code. The cross-correlation further includes detecting the end point of the preamble from the result of the digital cross-correlation. 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 the digital cross-correlation be performed iteratively in a block-by-block fashion. The computation of each block is split into M slices which are computed by algebraically summing windows N/M samples long.

Abstract: A method for encoding wideband speech includes sampling the speech to obtain successive voice frames each comprising a predetermined number of samples, and determining for each voice frame parameters of a linear prediction model. The parameters include a long-term excitation word extracted from an adaptive coded directory, and a short-term excitation word extracted from a fixed coded directory. The extraction of the long-term excitation word is performed using a first weighting filter. The extraction of the short-term excitation word is performed using a second weighting filter cascaded with a third weighting filter. The first and third weighting filters are equal.

Abstract: A method for encoding speech includes sampling speech to obtain successive voice frames each having a predetermined number of samples, and determining parameters of a linear prediction model for each voice frame. The parameters include a long-term excitation word extracted from an adaptive coded directory using a first linear prediction filter and an associated long-term gain. The parameters further include a short-term excitation word extracted from a fixed coded directory and an associated short-term gain. The adaptive coded directory is updated based upon the extracted long-term excitation word and the extracted short-term excitation word. The first linear prediction filter is updated using the short-term excitation word filtered by a second filter. The second filter has an order greater than or equal to 1 and coefficients thereof depend on the long-term gain for reducing a short-term excitation contribution when a long-term excitation gain is greater than a threshold.

Abstract: A controllable pulse generator generates the pulses of the signal which are respectively contained in successive time windows, and a control device formulates a control signal for the generator including, for each pulse, an indication of its position in the corresponding window. The control device includes a processor to deliver for each time window, at a delivery frequency Fe greater than the pulse repetition frequency, successive groups of N bits together defining a digital cue of position of a pulse inside the window. Also, a converter converts this digital position cue into the control signal temporally spread over the length (T) of the window and including the indication of position at an instant corresponding to the digital position cue. This makes it possible to position the pulse inside its window with a temporal precision equal to 1/N.Fe.
