Claim Text:
1. A transmission method for transmitting at least one multicarrier signal made up of Orthogonal Frequency Division Multiplexing Offset Quadrature Amplitude Modulation (OFDM-OQAM) symbols to a receive antenna of a receiver device, said transmission method being for use by a transmitter device having at least one transmit antenna, said transmission method comprising, for each transmit antenna of the at least one transmit antenna of the transmitter device, the processes of: filtering, using the transmitter device, the OFDM-OQAM symbols associated with the transmit antenna using a time-reversal prefilter defined from an estimate of the transmission channel between said transmit antenna and said receive antenna; and transmitting, using the transmitter device, the filtered OFDM-OQAM symbols via said transmit antenna over said transmission channel.
