Abstract: A transmission band of an analog signal including successive symbols to be transmitted is notched, where each symbol includes sub-carriers to be modulated. In particular, in each symbol the sub-carriers corresponding to a part of the transmission band to be notched are suppressed. In addition, in each symbol a chosen part of the remaining sub-carriers to be modulated is also suppressed.

Abstract: The transmission band of an analog signal to be transmitted is notched, including sub-carriers to be modulated from digital modulation coefficients respectively associated with the sub-carriers. The method includes providing an initial digital signal from successive frequency-domain groups each containing the digital modulation coefficients respectively associated to the sub-carriers. The initial signal is filtered with a frequency resolution greater than the frequency resolution of the frequency-domain groups to remove frequencies corresponding to the sub-carriers to be removed. The filtered signal is windowed using a windowing mask having a representation in the frequency-domain including a main lobe and secondary lobes. The power spectrum of the lobes decrease faster than the inverse of the frequency squared.

Abstract: A method for detecting an eventual channel intended to a designated user equipment among n channels received by the designated user equipment during a given duration, each channel received during the duration carrying encoded data masked with an identifier associated to a user equipment. The method includes a selecting phase having a demasking step demasking the received masked encoded data of each channel with the identifier of the 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 the channel from all the global information.

Abstract: A device for decoding an incident FEC encoded packet of data within an ARQ scheme. The device includes a processor or processing means for performing successive decoding processes of successive intermediate FEC code encoded packets related to the incident FEC code encoded packet. The processor or processing means includes a FEC decoder. The processor or processing means included a determination unit or determination means for determining initial decoding conditions from the FEC code decoding result concerning the preceding intermediate FEC code encoded packet and from the current intermediate FEC code encoded packet, and the FEC decoder is for performing the current FEC code decoding using the initial decoding conditions.
