Method of processing signal received by a radio interface having a number of multiplex channels by code spreading, includes estimating the response parameters of the multiplex channel

摘要

The method includes the steps of estimating the response parameters of a multiplex channel, and calculating the flexible estimations of symbols transmitted on the channel, as a function of the received signal and the estimated response parameters. The next step includes allocating the symbols whose flexible estimations which have been calculated between a first symbol assembly verifying a confidence criteria applied to these flexible estimations and a second symbol assembly which does not verify the confidence criteria. The next step includes determining a modified signal while removing the signal submitted to the previously calculated flexible estimation, from the corresponding estimated contributions respectively to the first symbol assembly, and calculating the new flexible estimations of the symbols of the second assembly, as a function of the modified signal and the estimated response parameters.
