Abstract
The embodiment of the invention is related to a processor configured for determining a predetermined number of frequency estimates, determining an average of the frequency estimates for obtaining an averaged frequency offset, unbiasing received samples and/or impulse response values using the averaged frequency offset, calculating Doppler frequency estimates using the unbiased received samples and/or impulse response values and calculating selected second order statistics of the Doppler frequency estimates over a predetermined period and calculating a speed of a communication system terminal using the Doppler frequency.
