Abstract: A method of, and system for applying frequency-domain equalization in a DS-CDMA system, either by augmenting the transmitted data block before it is scrambled by appending a prefix and a suffix known to or knowable by the receiver or by augmenting the transmitted data block after it is scrambled but prior to transmission so that it has a scrambled cyclic prefix. In the former case, the receiver synthesizes one of the prefix, the data block, or the suffix that would have been received if the augmented transmitted data block after scrambling had had a cyclic prefix.

Abstract: A method of a receiver determining the timing of a signal transmitted in a time-slotted manner, the signal comprising a sequence of information which is repeated at a known interval and has at least a known minimum length. The method performs correlation operations between groups of received slots of information, the groups spaced by the known interval. The groups are moved through the received signal, adding and removing slots, to locate a maximum correlation value sum for the group which should correspond to the timing of the slot. The method also can be used to determine a frequency offset at the receiver and/or an initial phase.
