摘要： A method enabling a multiple sensor equalization in a radioelectrical receiver including a specified number of reception antennas, the method including the steps of estimating the transmission channel on each of the antennas; estimating the background noise component plus interference on each of the antennas on the basis of the estimation of the transmission channel; estimating the spatial correlation matrix referenced R.sub.b of the background noise component plus interferences from the received signal; computing a spatial-temporal filter formed for each discrete temporal element of the estimated multiple-sensor channel of a spatial filter; achieving a temporal filtering of the data elements on the different sensors by the spatial-temporal filter; and equalizing the signal at output of the spatial-temporal filter by one-dimensional equalization at a symbol rate deciding the symbols transmitted.

摘要： The process according to the invention consists, in order to reduce the number of coefficients of the filters of the spatial part and the temporal part connected to the output of the spatial part, in jointly adapting the coefficients of the filters of each part using an adaptive algorithm according to the paths selected on the basis of a determined criterion. The coefficients are periodically recalculated at the rate of the known symbols in the learning sequences in order to minimize the estimation error apparent between a response signal (d(t)) and the receiver output signal (z(t)).

摘要： A process for calculating on the one hand the coefficients of a spatial filter applied to the signals emanating from the third step and on the other hand the coefficients of a temporal filter applied to the replica signal, made up either of the known symbols for the learning sequences, or from the demodulated symbols for the information sequences, the coefficients of these two filters being calculated so as to minimize, under a specified constraint, a criterion of mean square error between the output signal from the spatial filter and the output signal from the temporal filter, and consisting in filtering the signals emanating from the third step with the aid of the thus calculated coefficients of the spatial filter, thus optimizing the gain of the array of sensors in the direction of the useful signal at the output of the spatial filtering and ensuring rejection of the interference. The signal (y(t)) obtained at the output of the spatial filtering subsequently undergoes one-dimensional equalization at a symbol rate deciding the symbols transmitted, the coefficients of the spatial and equalizing filters being updated according to a specified sequencing.
