SPEED DETECTION METHOD IN COMMUNICATION SYSTEM, RECEIVER, NETWORK ELEMENT AND PROCESSOR

摘要

A speed detection method in a communications system, a receiver, a network element, and a processor, the 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 (300), means for unbiasing received samples and/or impulse response values using the averaged frequency offset (300), means for calculating Doppler frequency estimates using the unbiased received samples and/or impulse response values (302) and means for calculating selected second order statistics of the Doppler frequency estimates over a predetermined period (304).
