摘要:
The invention relates to a method for transmitting digital data over a communication channel, between a transmitting base including N transmitting antennas and K receivers. A carrier signal of frequency f 0 and M sub-carriers of index m are used, which are suitable for transmitting, in parallel, K digital data streams sk between the transmitting base and each receiver. The method includes a step in which N.M complex symbols t n (m) are calculated from K.M symbols s k (m), by t n (m) = formula (I) α k .H k,n * (m).s k (m), where * denotes a complex conjugate value, H k,n (m) is a complex value estimating the transfer function of the communication channel between the transmitting antenna n and the receiving antenna k, at a corresponding frequency of the sub-carrier m, and α k is a standardizing coefficient.
