Method for transmission by a base station equipped with a multi-element antenna to a mobile |
摘要 |
According to this method for transmitting a digital signal by a base station equipped with a multi-element antenna to a mobile, in the presence of interference sources and background noise, at least one frequency transposition operator is calculated which approximately transforms one reception calibration table into one transmission or reception calibration table; statistical data are calculated on the basis of the signals received by the various elements, originating from the mobile and the interference sources; for this mobile, an optimum set of spatial weightings is calculated on the basis of the statistical data, the frequency transposition operator, and a criterion for reinforcing the useful signal and reducing the interference sources; the digital signal is weighted on the basis of the optimum set of weightings, then it is transmitted.
