摘要： Disclosed is a transmission method of transmitting at least one multicarrier signal made up of OFDM-OQAM symbols to a receive antenna of a receiver device, the transmission method being for use by a transmitter device having at least one transmit antenna. In one embodiment, the method comprises, for each transmit antenna of the transmitter device, filtering OFDM-OQAM symbols associated with the transmit antenna using a time-reversal prefilter defined from an estimate of the transmission channel between the transmit antenna and the receive antenna and transmitting the filtered OFDM-OQAM symbols via the transmit antenna over the transmission channel.

The method includes, for a block of real data: a first modulation by a first modulator of the first M/2 data, delivering a first set of modulated carriers; a second modulation by a second modulator of the following (nb−1)·M data, delivering a second set of (nb−1)·M modulated carriers; a third modulation by a third modulator of the last M/2 data, delivering a third set of modulated carriers; and a superposition of the first, second and third sets, forming a block of OFDM/OQAM symbols of length nb·M/2, the first set being superposed with the start of the second set and the third set being superposed with the end of the second set.

摘要： 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.

摘要： A method is provided for modulating data symbols, outputting a multi-carrier signal, implementing: a mathematical transform, which transforms data symbols from the frequency domain to a time domain, outputting transformed symbols; and a polyphase filtering, which filters the transformed symbols, outputting the multi-carrier signal. The polyphase filtering uses an expansion factor taking account of a compression factor τ, the compression factor τ being a number between 0 and 1 such that the multi-carrier signal can be transmitted at a Faster-Than-Nyquist rate.
