Abstract: In this paper, the problem of recovering information from a receiver by Code-Division Multiple Access (CDMA) is investigated. To recover information from a spreading code modulation, despreading is performed by applying a replica of the original spreading code signal. If there is no apriori information about the time position of the spreading code modulation at the receiver, the probability density of the true position can be takeen to have a uniform distribution. A code synchronization process is employed to recover the original information.
