  • Method for producing a multi-carrier signal, device, and corresponding computer program
    Patent number: 10778491
    Abstract: A method for generating a multicarrier signal formed by a temporal succession of multicarrier symbols, implementing the following steps for generating at least one block of multicarrier symbols: coding a set of information elements delivering a set of coded elements; puncturing a first sub-set of coded elements of the set of coded elements, according to a first puncturing pattern, delivering a first sub-set of punctured coded elements; puncturing a second sub-set of coded elements of the set of coded elements, complementary to the first sub-set, according to a second puncturing pattern, delivering a second sub-set of punctured coded elements; mapping, onto at least one complex symbol, of the punctured coded elements of the first and second sub-sets of punctured coded elements; and generating the block of multicarrier symbols from said at least one complex symbol.

  • Precompensation of interference induced by an OFDM/OQAM modulation that is faster than Nyquist
    Patent number: 10404498
    Abstract: The invention relates to precoding (or rather pre-equalization) for a faster-than-Nyquist OFDM or OFDM/OQAM type transmitter. Compression of faster-than-Nyquist OFDM pulses over time introduces an inter-symbol interference (ISI) and a sub-carrier interference (ICI). Assuming a Gaussian-type channel (AWGN), the ISI and ICI can be estimated at the transmitter and, in this way, some of the symbols (at most half) can be precoded (according to the value of the adjacent symbols), such as to cancel the ISI and ICI introduced during transmission and reception.
