METHOD AND DEVICE FOR ESTIMATING FREQUENCY OFFSET OF MICROWAVE COMMUNICATION SYSTEM CHANNEL

Disclosed in an embodiment of the present invention are a method and device for estimating a frequency offset of a microwave communication system channel, the method comprising: upon performing a frequency offset estimation, conducting a correlation calculation on a received sequence and a local preamble of a main path to obtain a channel response; converting the obtained channel response to a frequency domain according to G set frequency points, and calculating to obtain the power of each frequency point, G being greater than or equal to the preamble length L of the microwave system; and determining the frequency point corresponding to the maximum power value, and calculating to obtain a frequency offset value of the main path according to the frequency point. La présente invention concerne, conformément à un mode de réalisation, un procédé et un dispositif pour estimer un décalage de fréquence d'un canal de système de communication par micro-ondes, le procédé consistant à : lors de la réalisation d'une esti
