摘要

Method for setting delay code of dispersion in derivations of rake receiver, and the receiver rake ".The invention relates to the establishment of delay codes of dispersion in derivations of a rake receiver.The signal intensity is determined (300) to a set of points of delay spread in the vicinity of each derivation rake.The change of retardation of code in each derivation is restricted (302) so that the changed delay is within an area, in which the signal intensity can be estimated by virtue of measurements.The differences between the code delays are restricted (304) to exceed a preset value.The solutions are determined (306) to the delay of code that includes a code candidate delay for the derivation to be processed and in the order of the previous derivations of retardation.The solutions maximize the sum of the intensities of signals in the derivation to be processed and in the preceding derivations.The delay of the derivations are selected (308) according to the last solution determined.
