Patent ID: RE40716

Claim:
A receiver for code distribution multiple access transmission and parallel multiple access interference suppression, the receiver comprising: at least one multiple access interference suppression stage ESI i constituted by K channels, each comprising a correlation means corresponding to a particular pseudorandom sequence, an interference estimation means and an interference suppression means, each stage delivering to a following stage K signals at least partly freed from multiple access interferences, a final, decision stage (ED) constituted by K channels receiving the K signals from the K channels of a preceding suppression stage and each comprising a correlation means corresponding to one of the pseudorandom sequences and decision means delivering a data item, means for producing synchronization signals able to control the at least one multiple access interference suppression stage and control the decision means of the final stage (ED), said receiver being characterized in that the means for producing the synchronization signals are constituted by K means solely placed in the K channels of the final stage (ED), the K synchronization signals produced by said K means controlling the K decision means of the K channels of the final stage (ED) and the interference estimation means of the K channels of the at least one interference suppression stages ESI i following appropriate time shifts.
