    Abstract: The device for decoding an incident FEC encoded packet of data within an ARQ scheme, comprises processing means for performing successive decoding processes of successive intermediate FEC code encoded packets related to said incident FEC code encoded packet, said processing means including a FEC decoder. Said processing means comprises determination means (DIL2, IM, SW1, SW2) for determining initial decoding conditions from the FEC code decoding result concerning the preceding intermediate FEC code encoded packet and from said current intermediate FEC code encoded packet, and said FEC decoder (FECD1) is adapted to perform the current FEC code decoding using said initial decoding conditions.

    Abstract: The method of notching the transmission band of an analog signal to be transmitted and including sub-carriers to be modulated from digital modulation coefficients respectively associated to said sub-carriers, said method comprises providing (30) an initial digital signal from successive frequency-domain groups each containing said digital modulation coefficients respectively associated to said sub-carriers, filtering (31) said initial signal with a frequency resolution greater than the frequency resolution of said frequency-domain groups in order to remove frequencies corresponding to said sub-carriers to be removed and windowing (32) said filtered signal using a windowing mask (WMSK) having a representation in the frequency-domain including a main lobe and secondary lobes, the power spectrum of said lobes decreasing faster than the inverse of the frequency squared.

    Abstract: Method for blindly detecting a channel:, like e.g. a HSDPA high speed shared control channel, possibly intended for a designated user equipment among n channels (HS-SCCH1,...,HS-SCCHn) received in parallel by said designated user equipment during a given duration, each channel (HS-SCCH1,...,HS-SCCHn) received during said duration carrying encoded data masked with an identifier associated to a user equipment. The method comprises a selecting phase comprising a demasking step demasking the received masked encoded data of each channel with the identifier of said designated user equipment, a decoding step decoding the demasked encoded data of each channel to obtain a set of digital decoded data for each channel, a calculating step calculating, from each set of digital decoded data, a global information representative of a confidence in digital data received on the physical channel, and a detecting step detecting said channel using said global information.
