The present invention relates to a method for equalizing modulation symbols transmitted on a non-linear transmission channel. The equalizing method operates on a sequence of observables, each non-linearly depending on a predetermined number of consecutive modulation symbols, and is based on a Viterbi algorithm. It comprises a prior step of receiving a pilot sequence of modulation symbols and storing corresponding observables (110), said pilot sequence leading to a path passing through all the branches of the lattice.In a second step (120), for each symbol to be equalized, for each branch, a branch metric is calculated as a distance between the observable corresponding to the modulation symbol to be equalized and the observable stored for said branch.

摘要:
A semi-automatic method for making a Li-ion electrochemical accumulator according to which a continuous electrolytic separator strip is automatically wound on two-sided electrodes manually and alternately stacked according to their polarity. By the method, it is not necessary to assemble or manually cut out each electrolytic separator inserted between two adjacent electrodes in the stack and of opposite polarity.

摘要:
The multiaxial inertial sensor of movements is a micro/nano sensor that makes it possible to couple at least one accelerometer with other structures, either accelerometers or gyroscopes, by an oscillating disk structure. The oscillating disk also forms an inertial sensor such as a gyrometer. This single-chip structure associating both gyroscopes and accelerometers makes it possible to achieve detections and measurements in up to 6 axes, in other words 3 accelerometer axes and 3 gyroscope axes, and to exert control by a single and unique electronic unit, thus permitting a single automatic control loop in excitation and a single electronic reading chip.Application to technologies known as MEMS.
