1. A method for performing measurements in a wireless terminal comprising:
- receiving radio frequency signals;
taking samples (i,q) from the received signals; and
performing measurements on the basis of said samples, wherein the samples taken from the received signal are stored and measured values are calculated for the stored samples after a set of samples has been stored, andwherein the measured values are used to search for a carrier wave in the received signal.

17. A method for performing measurements in a wireless terminal comprising:
-
receiving radio frequency signals transmitted by a base station of a mobile communication network, in which frequency correction bursts are transmitted on a frequency control channel, taking samples (i,q) from the received signals, and performing measurements on the basis of said samples, in which method the samples taken from the received signal are stored and measured values are calculated for the stored samples after a set of samples has been stored, storing of samples and calculation of the measured value is repeated at intervals, wherein two or more samples are taken and stored between each successive calculation of the measured value, the calculated measured values are used for searching a carrier wave from the received signal, and the carrier wave to be searched for is a sine wave signal used in the transmission of the frequency correction burst.
