The invention relates to a method and device for the joint detection of data transmitted by direct sequence spread spectrum (DSSS). The device comprises means of using a Cholesky decomposition to calculate a matrix U such that: L=<H>xU, where L is an equalization matrix and U is an upper triangular matrix. The means for using a Cholesky decomposition comprise MAC cells (MAC1, MAC2, . . . , MACN) and a diagonal cell (DIAG) of a systolic network. The MAC cells and the diagonal cell are also used to calculate an estimated vector d of received data. For example, the invention applies to the field of digital mobile phone transmissions.
