A method and device for processing a received signal by detecting within the received signal a plurality of possible symbols transmitted by or for a plurality K of users, each of the plurality of possible symbols belonging to a modulation constellation and being the subject of a spectral spreading by a spreading sequence. The transceiver card is small in terms of spatial dimensions, has very good heat dissipation characteristics, and is capable of simultaneously transmitting and receiving data at a rate equal to or greater than approximately one Tb per second. The regrown layer 27 includes an electron transit layer 22 and an electron supply layer 26. The invention further relates to the inbred and hybrid genetic complements of plants of variety I539440. After forming the sourcedrain regions, a portion of the gate electrode between the first and second fins is removed to expose the isolation layer.
