Patent ID: 8031788

Claim:
A method of signal reception in a telecommunications network comprising the reception of a number P of signals on P respective antennas, where P is an integer strictly greater than 1; wherein said signals received corresponds to a multicarrier signal transmitted in the form of successive frames including symbols occupying respective positions distributed along an axis of time and along an axis of frequency; a frame including M blocks with each having at least N reference symbols, with the reference symbols in each of said blocks satisfying a first maximum spacing between them along the axis of time and a second maximum spacing between them along the axis of frequency respectively lower than a first value and a second value, N being an integer greater than or equal to P, M being an integer at least equal to two; wherein said method includes the following steps: /a/ determine, at the frame level, M groups of P weighting coefficients, each one of said M groups relating respectively to one of said M blocks of reference symbols emitted, said P coefficients of a group being respectively associated to the blocks of reference symbols which are received on the P antennas and which correspond to the block of reference symbols emitted relating to said group; said coefficients being determined so as an error value for each one of the M blocks of reference symbols emitted is lower than a threshold value, between on one hand the reference symbols of said block emitted, and on the other hand symbols obtained using symbols received on each of the P antennas at the positions of the reference symbols corresponding to said block emitted, respectively weighted by said associated weighting coefficients; /b/ obtain weighting coefficients applicable respectively to the signals received on the P antennas for the other symbols in the frame, by interpolating said weighing coefficient determined at step /a/; /c/ generate a composite signal by summing up the symbols received respectively on each of the P antennas and corresponding to a same symbol emitted in the frame, each one of said symbols received being respectively weighted by the associated weighting coefficient determined in step /a/ or obtained in step /b/.
