ABSTRACT:
A method for performing synchronization operations of a receiver to a received code-modulated spread spectrum signal whereby at least one reference code (r(x))is used. This reference code corresponds to a code used in the modulation. The frequency shift of the received signal and the code phase of the code used in the modulation are determined in the method. Hartley transformers are also used.
