摘要：
The embodiment of the invention is related to a processor comprising, for example, means for determining a predetermined number of frequency estimates, means for determining an average of the frequency estimates for obtaining an averaged frequency offset, means for unbiasing received samples and/or impulse response values using the averaged frequency offset, means for calculating Doppler frequency estimates using the unbiased received samples and/or impulse response values and means for calculating selected second order statistics of the Doppler frequency estimates over a predetermined period.
