Abstract: A method is provided for transmitting a digital signal via n transmit antennas, wherein n is strictly greater than 2. The method includes combining with a source data vector n vectors to be transmitted respectively by each of the transmit antennas by a coding matrix M with a yield equal to 1, using reference symbols known to at least one receiver whereby it is able to estimate at least three transmission channels corresponding respectively to each of the transmit antennas. The coding matrix M applies a mathematical transformation to the reference symbols prior to the transmission thereof.

Abstract: The invention relates to a method of determining the time shift and/or the power of a received signal incorporating a reference sequence (3) and transmitted by multicarrier modulation on a set (M) of carriers spaced from each other by a distance nΔf where n is a natural integer and Δf is a constant. An inverse Fourier transform is applied to the phase variations between components of the signal carried by carriers separated by kΔf for consecutive values of k in order to obtain the impulse response (RI) of the signal and the time shift τ0 and/or the power of the received signal is/are determined from the impulse response by observation of the highest level amplitude peak.

Abstract: A method is provided for receiving a received signal corresponding to a multicarrier signal transmitted by at least one transmitter via a transmission channel. The multicarrier signal is formed by a temporal succession of symbols consisting of a set of data elements including informative data elements with real values, and pilots for at least some of the symbols. Due to groups of at least two pilots being respectively located in an adjacent region in the time/frequency space, the reception method includes a step of extracting at least two complex values corresponding the pilots of the group of the adjacent region, once they have passed through the transmission channel, and a step of estimating the transmission channel in the adjacent region on the basis of the complex values. The modulation used is the type of OFDM OQAM.
