Abstract
The invention regards to Carrier recovery device, especially estimator device for carrier recovery, for pseudo random noise based systems, comprising a coarse estimator (), a fine estimator (), a switch () to select estimator output, and a sweeper () to sweep input data carrier frequency offset within a certain range, wherein the coarse estimator () is arranged to estimate a residual frequency offset by using a correlation of pseudo random noise (PN), and the fine estimator () is arranged to estimate the residual frequency offset by using an estimated channel information, and wherein the switch () is controlled to select data outputted out of the coarse estimator (), the fine estimator () or the sweeper () as the estimator output.
