2- TDOA/FDOA Reduced complexity TWO-STEP TDOA/FDOA estimation method for communication signals

摘要

The two-step TDOA and FDOA information extraction method according to the present invention comprises: a signal reception / processing / transmission step of receiving a signal using two or more antennas, performing a convergence and interpolation method, and transmitting the signal to a central processing unit; And an optimum sampling frequency changing step of calculating an optimal sampling frequency for the optimum calculation amount and changing the frequency of the transmitted received signal to an optimal sampling frequency. The present invention also provides a method for maximizing the transmission efficiency and drastically reducing the calculation amount while obtaining accurate estimation values .
