    • A system is provided for communications between at least two telecommunications devices, at least one being onboard an aircraft, said devices comprising means for sending and/or receiving digital data, said data being classed in at least two categories, the first category corresponding to critical data, the second category corresponding to non-critical data. The data are sent on M antennas and received on N antennas. A matrix H of dimension M×N representative of the multi-antenna propagation channel is estimated and the data are sent according to a mode of transmission selected from among at least two multi-antenna modes. A first robust mode uses a scheme of Alamouti type, a second high-speed mode uses a scheme of BLAST type. The critical data are transmitted using the robust mode, the non-critical data being transmitted using one of the two multi-antenna modes. The high-speed mode is selected when the rank RH of the matrix H exceeds a previously chosen threshold value SR.

    • The invention relates to a method of estimating symbols carried by a digital signal that is received by a receiver over a communication channel (5), said symbols being multiplexed or orthogonal frequency sub-carriers. The inventive method comprises the following steps in relation to each symbol carried by the digital signal, consisting in: performing at least two transforms towards the frequency domain (8,9) on a portion of the received signal essentially corresponding to the symbol, said transforms being performed with a determined time lag (10) therebetween: estimating the parameters (r0, r1, . . . , rn, r′0, r′1, . . . , r′n) of the communication channel from pre-determined binary information contained in the digital signal; and estimating the symbol from a combination of the result of each of the transforms performed and the estimated communication channel parameters.
