ABSTRACT:
A method for code tracking RAKE receiver fingers, the method comprising: taking several successive samples from a received signal, combining sample values measured in different fingers into measurement value sets, comparing the measurement value sets with each other and selecting the measurement value set having the highest value from among the measurement value sets meeting a minimum delay distance condition for the fingers, if any one of the sample values of the selected measurement value set is earlier than an on-time sample value determined on the basis of code phase acquisition, advancing the sampling or code phase of the particular finger, and if any one of the sample values of the selected measurement value set is later than an on-time sample value determined on the basis of code acquisition, delaying the sampling or code phase of the particular finger.
