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 7):
A method of receiving a multicarrier signal, delivering a set of estimated symbols, characterized in that it includes:\n step of demodulating ( 41 ) a set of carriers forming said multicarrier signal, delivering a first subset of demodulated precoded symbols and a second subset of demodulated non-precoded symbols, a step of time and/or frequency equalization ( 42 ) of the demodulated precoded symbols, delivering equalized demodulated precoded symbols, a step of time and/or frequency equalization ( 43 ) of the demodulated non-precoded symbols, taking into account an estimate of interference affecting said demodulated non-precoded symbols obtained from said equalized demodulated precoded symbols, delivering equalized demodulated non-precoded symbols.
