Abstract: An interface is described which has at least one chip side port with a first plurality of pins for conveying fields of a packet and first and second circuit side ports each port having a set of pins with a lower number than the first set of pins in the chip side port. The interface is constructed so that interrupt signals from an off-chip circuit can be conveyed on-chip in a manner such that the interrupt signals are indistinguishable from interrupt signals received from on-chip modules connected to an on-chip communication path. The same principle is applicable to power-down signals.

Abstract: A first estimate is made of the impulse response of the channel considered as a whole, then this first estimate is corrected independently of the information transmitted for obtaining a corrected final estimate of the impulse response of the channel. This is done by taking account of the fact that the impulse response of the sender and the impulse response of the receiver are known.

Abstract: A color filter array for an optical image sensor comprising pixels that are arranged in a matrix or a line, each pixel being connected to an electronic circuit for converting the information concerning the luminosity of each pixel into electric signals. A rectangular color filter of a predetermined color is placed over each pixel and several pixels that are directly adjacent form pixel by pixel with color filters of different colors a base cell, a plurality of said base cells together constituting the matricial or linear image sensor. The aim of the invention is to create a color filter array for an optical image sensor, which reliably prevents the distortion of the color signals by unfiltered white light. The object is achieved by making the border regions between adjacent color filters of different color significantly less permeable to light as a result of an overlap or additional non-transparent strips.

Abstract: A method for blindly detecting a transport format of a convolutional encoded signal is provided. The transport format is unknown and belongs to a set of MF predetermined reference transport formats. The method includes decoding the convolutional encoded signal using a Maximum-a-Posteriori algorithm. The decoding includes considering the MF possible reference transport formats and delivering MF corresponding groups of soft output information, calculating from each group of soft output information a calculated cyclic redundancy check (CRC) word, and comparing the calculated CRC word with the transmitted CRC word. Groups are selected which the calculated CRC word is equal to the transmitted CRC word, and an actual transport format of the convolutional encoded signal is selected from at least one soft output information among last ones of each selected group.

Abstract: The electrical consumption of a cellular mobile telephone is reduced by using fractional-division phase-locked loops receiving a frequency reference from a fairly inaccurate quartz oscillator. Electrical consumption is also reduced by switching the output of the oscillator onto the input of the processing stage when the transmission/reception stage is inactive. The fractional-division phase-locked loops can then be deactivated.

Abstract: A method for processing an incident pulsed signal of an ultra wide band type received over a channel by a data device operating in a wireless data communications system is provided. The incident pulsed signal carries information within a super-frame structure. Upon reception of each super-frame structure by a data device, coarse synchronization is performed with another data device acting as a coordinator device for the wireless data communications system. The coarse synchronization uses a first training sequence. Upon reception of each frame allocated to the data device operating within the super-frame structure, channel estimation is performed using a second training sequence. The channel estimation also performs a frame synchronization.

Abstract: A method for controlling frequency of a local oscillator in a DS-CDMA type receiver includes transforming a known spread spectrum signal into a sampled digital signal formed of symbols with a despreaded frequency spectrum, and determining a residual frequency error fe for each symbol including a first residual frequency error fe1. The method further includes correcting the frequency of the local oscillator with the residual frequency errors, and determining an average of absolute values of a predetermined number of successive residual frequency errors. The average is compared with a threshold, and if the average is greater than or equal to the threshold, the local oscillator frequency is corrected using an error equal to nullsgn(fe1) (1/Tnullnullfe1null), where sgn is the sign function, null null is the absolute value function and T is duration of a symbol before determining the next residual frequency error associated with the next symbol.

Abstract: A process for estimating a speed of movement of a mobile terminal operating in a wireless communication system and communicating with a base station via a transmission channel includes estimating fading of the transmission channel, and performing an autocorrelation on the fading for providing a first autocorrelation result. Reference autocorrelation results are calculated for predetermined values of speed of movement of the mobile terminal, with the calculating being based upon a known autocorrelation function performed on the fading. The process further includes comparing the first autocorrelation result to the various reference autocorrelation results, and estimating the speed of movement of the mobile terminal based upon the comparison.
