摘要： A signal is received in a telecommunication network in the form of P signals received on P corresponding antennas, where P is greater than or equal to 1. The received signals correspond to a multi-carrier signal transmitted in the form of frames comprising symbols occupying corresponding positions distributed along a time axis and along a frequency axis; a frame comprising M blocks each having at least N reference symbols. The reference symbols in each of the blocks satisfy a first maximum spacing between each other along the time axis and a second maximum spacing between each other along the frequency axis, less than a first value and a second value respectively, M being an integer number equal to at least two. M estimated noise power values are determined at frame level, each related to one of the M emitted reference symbol blocks. Values of the estimated noise power for the other symbols in the frame are then obtained from the determined estimated noise power values .

摘要： A signal is received by P antennas. It includes frames having symbols occupying respective positions distributed along an axis of time and of frequency, a frame including M blocks having N reference symbols. M groups of P weighting coefficients are determined, each one of the groups relating to one of the blocks emitted, with the coefficients of a group being associated to the blocks which are received on the P antennas and which correspond to the block emitted relating to the group. The coefficients are determined so as to increase via a threshold value, an error value for each block emitted, between the reference symbols of the block emitted, and the symbols obtained using the symbols received on each antenna at the positions of reference symbols corresponding to the block emitted and the associated coefficients. Then, weighting coefficients are obtained for the other symbols of the frame. Finally, a composite signal is generated by summing up the symbols received respectively weighted by the associated weighting coefficients.

摘要： A radio communication transmitter (EM) comprises at least two antennas (AE1, AE2) for transmitting a signal containing encoded bits which are converted into distributed symbols according to subcarriers and time intervals. The transmitter encompasses a signal splitter (REP) for splitting all the symbols of the signal into as many separate subsets (SEi) of signal symbols as the transmitter has antennas, each subset being allocated to one of the antennas and the combined subsets amounting to all the symbols of the signal. The symbols are split into at least two subsets during a time interval of the signal or for a subcarrier. The antennas each synchronously transmit the subsets of symbols. The subsets of symbols can comprise a number of substantially identical symbols to reduce a difference between peaks of strength and the average strength of the signal transmitted by each antenna.
