Abstract

The invention relates to a method for receiving spread-spectrum signals for fine time synchronization of correlators in a RAKE receiver. The objective of the invention is to produce a signal that is to be transmitted with the highest possible signal to noise ratio on the basis of the received signal. To achieve this, a higher level unit intervenes in the normal adjustment of a first basic time lag in a first RAKE finger and the normal adjustment of a second basic time lag in a second RAKE finger when the difference between the basic time lags of both RAKE fingers corresponds to a minimum level, and subsequently carries out a joint adjustment for both RAKE fingers, taking time error estimates for both RAKE fingers into account.
