Method for transmitting at least one multi-carrier signal consisting of OFDM-OQAM symbols

A reception method for receiving an Orthogonal Frequency Division Multiplexing Offset Quadrature Amplitude Modulation (OFDM-OQAM) type multicarrier signals including OFDM-OQAM symbols as transmitted by at least one transmit antenna of a transmitter device, wherein the transmitting device for each transmit antenna of the at least one transmit antenna performed filtering on the OFDM-OQAM symbols associated with the transmit antenna using a time-reversal prefilter defined from an estimate of a transmission channel between said transmit antenna and a receive antenna in order to generate and subsequently transmit the OFDM-OQAM signals, the reception method comprising:

• receiving, using the receive antenna at a receiver device, an OFDM-OQAM type multicarrier signal corresponding to the sum of the OFDM-OQAM type multicarrier signals received from each of the at least one transmit antenna of the transmitter device;
• and
• demodulating, by a demodulator in the receiver device, said received OFDM-OQAM type multicarrier signal corresponding to the sum of the received OFDM-OQAM type multicarrier signals received from each of the at least one transmit antenna in order to recover the corresponding OFDM-OQAM symbols.

A transmitter device having at least one transmit antenna and configured for transmitting at least one Orthogonal Frequency Division Multiplexing Offset Quadrature Amplitude Modulation (OFDM-OQAM) type multicarrier signal via said at least one transmit antenna of said transmitter device to a receive antenna of a receiver device, said transmitter device comprising in association with each transmit antenna:

• a filter in said transmitter device which filters OFDM-OQAM symbols associated with that transmit antenna, said filter comprising a time-reversal prefilter defined on the basis of an estimate of a transmission channel between said transmit antenna and said receive antenna;
• said transmitter device being configured to transmit the filtered OFDM-OQAM symbols via said transmit antenna over said transmission channel.

• a receiver and the receiving antenna for receiving an OFDM-OQAM type multicarrier signal corresponding to the sum of the OFDM-OQAM type multicarrier signals received from each of the at least one transmit antenna of the transmitter device;
• and
• a demodulator for demodulating said received OFDM-OQAM type multicarrier signal corresponding to the sum of the OFDM-OQAM type multicarrier signals received from each of the at least one transmit antenna in order to recover the corresponding OFDM-OQAM symbols.
