Abstract
A method of conjoint detection of a set of CDMA codes received at a plurality of antennas of a receiver like a mobile telephone receiver. The codes are transmitted via a transmission channel with transfer matrix A satisfying the equation e=A.d+n, where d is the set of symbols of the codes transmitted, n is an additional noise vector and e is the set of received samples. For a transfer sub-matrix A.sub.S corresponding to a number S of rows of blocks of the transfer matrix A, a set of equalising filters are determined for successively estimating all the symbols transmitted by the CDMA codes on the basis of a particular number of received samples
