Abstract (en)
[origin: WO2005053212A1] A method for increasing the capacity of signal transmission systems comprising NT users and a monobloc receiver receiving a mixture of signals from NT users, consisting of the following steps: determination of qualitative information Info(Qs) relating to estimated symbols for each NT user; transmission of said information Info(Qs) to a processing unit which receives information a priori and which is adapted in order to generate quality information Info(Qbs) on the bits making up said symbols; transmission of the Info(Qbs) to a decoding stage in order to obtain qualitative information on the coded bits and Info(Qbu) on the useful bits.
