Abstract: A method for MC-CDMA transmission of data between nodes of a network, including assigning to each node at least one spreading matrix, a set of data of at least one datum to be transmitted by a node being multiplied by the spreading matrix which is associated therewith and the product being then transmitted on a group of carriers in at least one predetermined set of samples forming at least one OFDM symbol; forming symbols to be transmitted all having the same duration, whatever the transmit node; and adding to each transmitted symbol a cyclic prefix and a cyclic suffix representing a predetermined number of samples, respectively of the end and of the beginning of the symbol.

Abstract: An image sensor pixel structure including: a photosensitive area surrounded with a peripheral area placed at the surface of a semiconductor substrate, a stack of several insulating layers alternately exhibiting different refraction coefficients and placed above the peripheral area, a microlens placed at the top of the pixel to have the pixel light converge towards the photosensitive area, and a transparent block placed substantially above the photosensitive area.

Abstract: A decoding circuit and associated method are provided for decoding a biphase signal. The decoding circuit may include a precharging register to precharge a pair of states of the biphase signal, where a state of the pair of states is precharged at each pulse of a periodic precharging signal. The decoding circuit may further include a verification circuit to compare the two states of the pair of states and give an active error signal if the two states are equal.
