Method in the synchronization of a receiver, and a receiver
First Claim
1. A method for synchronizing a receiver with a signal modulated with a spreading code, in which method the frequency shift of the transmitted signal and the symbol acquisition of the data transmission are determined, and wherein guessed data is formed, and the received signal is multiplied with at least two different values of said guessed data to form spectrum results, wherein the frequency shift is determined on the basis of the spectrum results formed with said different guessed data.

Abstract
The invention relates to a method for synchronizing a receiver with a signal modulated with a spreading code. In the method, the frequency shift of the transmitted signal and the symbol acquisition of the data transmission are determined. In the method, a guessed data is generated, and the received signal is multiplied with at least two different values of said guessed data, to form spectrum results. The spectrum results formed with said different guessed data are used to determine the frequency shift.
