Abstract:
The invention relates to precoding (or rather pre-equalisation) 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.

Claim (Index 1):
A method of generating a multicarrier signal, from a set of symbols, characterized in that it includes:\n a step of precoding ( 31 ) a first subset of symbols of said set of symbols, delivering a first subset of precoded symbols, said step of precoding ( 31 ) modifying the value of a symbol of said first subset for taking account of interference generated on this symbol by at least one other symbol of said set of symbols intended to be transmitted at the same instant or at the same frequency according to a predetermined time/frequency transmission pattern, and a step of modulating ( 32 ) a set of carriers from said first subset of precoded symbols and a second subset of non-precoded symbols of said set of symbols, delivering said multicarrier signal, said step of modulating ( 32 ) modulating each carrier of said set of carriers by a precoded symbol of said first subset or by a non-precoded symbol of said second subset according to said predetermined transmission pattern.
